I have a history of some minor lower back problems. I'm generally healthy, fit, and capable of anything, but I do need to be smart about how I use my lower back.
Although I have read everything I can fidn on the subject, I'm also someone who has ZERO experience with vertical caving, so don't really know first-hand what works best in different situations.
My *guess* is that a rope-walker system would minimize stress on the lower back when compared to a frog system.
I am planning to attend a vertical intro class soon, and need to figure out what equipment I need to order.
Thanks for any info or suggestions.
