Hmm, most gyms are too well protected, if anything. We got a new route setter just this year that is setting some riskier ones, trying to traverse and shit to make the routes longer and more interesting. I end up skipping clips fairly often, but I understand most gyms would freak out about that.
To be honest, I like to climb in a gym where there is a little risk involved...
As far as TRing, I HATE reclipping the bloody directional draws on the overhangs on the way down, I'd rather lead it. And, to reiterate, it is a waay better exercise.
