And after maybe 10 or 20 years your shoulders will be pulled apart and you might not be able to shoot at all. Now that is what gets boring.

I found out the hard way. Although I didn't need shoulder surgery I find that the weight keeps coming down. Right now I order 55# limbs and shoot between 52# and 55#.

Frankly you don't give up very much speed at all if your arrows are weightedproprtionatelyto the bow poundage. You may give up some kinetic energy, but accuracy is far more important. Heck, I've had bows shooting 300 fps at 27" draw and 53# shooting at 5gr/lb.
