In reply to: OP, did the leader top belay you after he reached the top or something?.. it could make more sence. No it was indoors. When we got to the top we were simply lowered to the ground.
In reply to: Or was the guy simply giving you info on how people do things in a situation you did not realy need to know about their and then?. He didnt give me any situations. Thank you for all your replies, it sounds like this technique is quite normal in the UK (where I am from). However as I am new to leading and currently only lead climb indoors I might stick to the belay loop.

Sticking to the belay loop isn't going to hurt. Plus, the reasons you were given for the rope loop are all bogus and are, if I recall, debunked in the article on the UKC site I linked above. I think the rope loop belay is superior in two situations. (1) Belaying the second from above from the harness, and (2) catching a factor-2 leader fall. Both of these are multi-pitch situations (one of which most climbers never experience) so you don't have to think about the issue until you're more experienced. On a more estoteric note, the potential for rolling a "cross loaded" figure-8, I forgot to mention that, since the loads are coming on a loop, the knot itself is only getting half the impact force. Moyer's tests suggest that a well-tied figure-8 can roll at 750 lbf, which would mean the rope loop would need a rather hefty 1500 lbf for rolling to occur. At that level, there is no doubt that the belayer is going to be yanked hard against the anchor, in which case tension on the anchor strand will, I think, make rolling impossible. This is, of course, doubly hypothetical in the presence of a back-up knot on the figure-8. So all in all, there's really nothing to worry about.

That assumes you are tied into the belay with the rope on a multipitch route. That's not what I was referring to. I was referring to simply using the rope loop in place of the belay loop in a general scene. If you are tied into the belay with slings or on a single pitch route, you are not tied into anything with the rope, so you are loading only the rope loop.

One concept everyone here seems to be missing or unaware of is that using the tie in loop to belay off of is very dangerous in the case of using a "Yosemite finish". Apparently the roll over threshold is vastly reduced and because of the orientation of the free end back through the knot, it will fail on the first roll. A climbing mag (Gripped or Climbing, I don't remember) did some tests and warned against the Yosemite Finish for this purpose. Otherwise it seems fine to use the tie in loop, (not that I do). But the BELAY loop works great for BELAYING! On a side note. Using the tie in loops to belay off of is a less than great ideal. It rotates the belay device 90* and would cause a gri gri, cinch or smart to behave weirdly. An "atc" style device is less effected, but why????? Your 25 Kn belay loop Isn't going to fail. And if your worried it might, it's probably cus your harness is tattered and old, buy a new one dirtbag .

As a non-user of figure-8's, I wasn't aware of the effects of various "finishing" techniques on the rolling of the knot. It seems that the main drawback of the figure-8, the difficulty of untying it after loading, has led to some "finishing" techniques that have the far worse side-effect of making the knot far more unstable under ring-loading. Tying a double overhand knot with the short strand on the load strand will back up a figure-8 to the bombproof level as far as ring-loading is concerned. But if the problem to be avoided is untying difficulty, then another knot is a better idea than messing with the figure-8 by adding extra turns and tucks. As Jim says, a rethreaded bowline on a bight is better than a figure-8 anyway, but convention being what it is, it seems unlikely that anything more than a fringe group of cognoscenti will adopt that knot. Edit: Corrected the misspelling "cognescenti" after being alerted to it by Jay.

I was doing a required 'induction' at a wall close to where I've just moved - the guy asks me to set up a belay, which I do as I always have done, from the belay loop. He then runs over and says NO NO NO! Always belay from the rope loops, it gives a more dynamic belay. Made me look like a fool in front of a class he was teaching. Jobsworth. Didn't want to argue with him so I did it that way, a tiny rope loops isn't going to have much stretch though, right?! And a knot tightening is not going to be the decider on a fall now is it... Belay loop it is for me.

I guess that's why it said "side note", huh? Rotates 90* and loop(s) should also have been the key phrases. No worries. The other one that bugs me is people who clip directly to the thumb loops of cams instead of the chain because it "takes one more link out of the chain that could fail" (not talking about aid here) even though most brands (especially BD) specifically warn that this lowers the strength of the cam. Humm . . . lets see, lower a 14kn cam to 10 kn? Or trust a 22kn sling? Tough one. Anyone else have examples of uses of gear opposite to the manufacture's instructions. (ie, not trusting a belay loop for belaying.)

For what it's worth, here is a worst-case scenario argument for clipping into both the rope loop and the belay loop. It is an excerpt from a short piece written back in the 1990s by Tom Jones (a harness deisgner for Black Diamond at that time).
Tom Jones wrote: This brings up why it is important to clip your belay device into both your belay loop and the loop of the rope on multi pitch climbs. The lead rope should be your primary anchor - your primary link from your harness to the anchor - because it is dynamic and flexible. Your belay biner should connect directly to the rope tie in loop so that the forces of the belay can link directly to the anchor. Otherwise, the forces from a severe fall would run from your belay biner to the belay loop, to the harness, to the rope loop to the anchor. This would tend to rip the harness apart and the results are very unpredictable. It is much better to have the forces transfer as directly as possible to the strong point in the system - your fully equalized, three bomber pieces anchor.
