Thanks for explaining that, I was a little confused as to how that would work, but now it makes perfect sense. I will have to try that with my recurve.
I was thinking more on the line of the 80% let-off for the thumb's sake.
Watch the Thumb with that Recurve, it a lot like the Bow the Ancient Mongols used, & one would envisage they started training at about the ripe old age of 2 yrs. & sometimes jacked the power up to 140#.
