I have a Gri Gri and a Cinch as well as just purchasing a SUM. I dont use ropes fatter than 10-10.2mm.
The SUM like any device takes a little to get the hang of (a quick 5 min tute will generally do it).
PRO's- Pays rope out fast, easy to take rope in quickly, bites hard and quickly onto the rope when the leader falls.
CONS-No good at ALL for rapping. Its easy to put rope in 'upside down'. Fatter ropes (ie >10mm) dont run that easily thru the device.
All in all its the best device for peeps who use sub 10mm rope. The SUM pays out faster than a Gri Gri and is easier to lower off the leader when they have fallen, compared to the Cinch.
I have sold my Cinch and only use my GriGri for rapping or new route setting.
