Mike done me good too. I went with the cmi ascender and he mounted it right to the shank, really nice because the line runs clear of the spike, and is totally out of the way for normal spurring action. Really solid attachment.
I've only been using it for a few weeks, and been doing lots of pruning, but it's awesome, no more messing with cumbersome foot ascender underneath hooks. I hope to get some action shots or video up soon!
Thanks again Mike!
