well, it may be that he uses poly for the spin potential, which remains largely unaffected when the strings go 'dead'
I use poly because I like it, not because I 'need' it, I am not convinced anyone truly 'needs' it if they are changing it out after 10 hours anyway...
(or do you really hit so hard you break anything else in that time?)
for the record, I don't have a set amount of hours, if I pick up a frame and its dead, I change 'em, but I don't really know how long that takes because I just grab the first frame to hand from my bag and they are all strung the same but at random intervals..(ie, if one feels bad, I cut it out, ok, break 'em on the net post, right then and there!)
