I think the climber you use has a ton to do with how safe and comfortable you feel. If yours isn't a sit down/stand up climber I suggest you get one.

I'm a big(fat) dude that probably shouldn't be climbing laugh and until I bought my first Summit Goliath I never felt totally safe. Now I can shimmy up there as good as a big guy can and sit there safely and comfortably. Scape you up some cash and get you a Summit Goliath and I'll bet you'll feel much different about it.
