I have started to climb the slabs on Breakneck wearing my climbing shoes and a helmet as my only gear. It's not necessarily a technical climb....but it is as close to free soloing that I've come and there are sections that if you do fall...it's a long way down and you are going to get hurt.
I have found that I like the feeling and the challenge...but I am extra careful to not make a move without knowing I can reverse it. There is a lot more mental energy that I expend.
I have to say though, that it is a thrill.
