I've been watching this thread and I'd urge caution making statements like this. It has nothing to do with wanting or not wanting to learn hitches and everything to do with personal preferences and comfort levels. I've climbed fire towers SRT using only hitches passing knots, doing changeovers and descended using hitches but only use mechanicals while hunting.
The reason solely has to do with speed, convenience and a degree of comfort level. I don't want to tie various hitches before I climb or descend. I have no issue with someone calling that as being lazy because it is. However, I am 100% confident that I can attach a mechanical in the pitch black, under any weather condition and wearing any type of glove quickly and silently. I also carry hitch cord with me in case I drop, damage or misplace said mechanicals but they serve as a backup.
Pressuring new climbers one way or another is akin to forcing a new shooter to use a 300 winmag when a 243 will work just as well. In the end, neither one is better and each have their pros and cons.
