Ampa,
Actually my STS is a front mount one that I bought when I had my Grizzly so I have no interference at all with my wrist. Have you tried just mounting so its a little lower on the string? Getting back to the windstalker, if you don't mind where did you buy it and what do they retail for in Ontario? I find I have some vane contact with the cables so either I switch sliders or find a better solution which the Windstalker is probably I would think. And hey any increase in speed is never a bad thing either.Was there any tuning difficulties after eliminating the factory cam lean caused by the rod and slider? Is it quiet ? Sorry for all the questions.
