Chris, you didn't really dig em' for pruning? Most of my climbing is for pruning, with a removal mixed in here and there. I don't spend too much time on gaff's (now watch this change for the 2011 season, because I just jinxed it!)
In the past, I have tried everything from Redwings (last 18 months) Rockys, Timberlands, and Caterpillars. All of these leather boots really limited flexibility during my climbs. So I tried a new approach last season which worked, for the price of 1 pair of Redwings, I bought 3 pairs of cheap-o hiking boots which I would just rotate, or replace once they were too far gone. Light, breathable, and FLEXIBLE!
I guess I, along with every other climber out there is looking for the holy grail of boot.
