Not safe at all! (to lower that is.0
You are using at least 4 to 6 feet of rope to tie the rope into your leader and to the belayer. Or at least you should be in the habbit of tying into your belayer as well as the leader to avoid running out the last of your rope through the belay device while belaying 30M+ routes.
I have to agree with some of the other posts that this thread is becoming alarming at an increasing rate. Perhaps for your safety it would be wise to slow down a bit and have some one show you the techniquies involved in this process.
