While there are lots of approaches most archers (or is it just me) seem to like the wall on modern bows. This is a point where the drawlength appears to bottom out solidly. By pulling against this wall, it shouldn't mater what the holding weight is, since you are pulling through to whatever degree of resistance seems solid.

While there are some dual cam devotees here (I own two) single cams have generally proven a lot less trouble relative to timing. It may be that Bowtech has this problem licked either with adjustable cables, or better cables (two systems imply to me they are searching), but it is an advantage of the single cams I know that they don't have this problem, and that minus the adjusters, you don't need a press to tune them just so. For mega great big bertha super tuning, fiddling with dual cam timing may be just the thing. I don't miss it.

There is probably no problem greater than being overbowed as far as killing your accuracy potential. One of the problems with it is that most people seem prone to being overbowed, and other than the fact one isn't shooting up to one's potential, people do not seem to diagnose the problem. High let-off bows do not cure being overbowed, lower peak draws, or total energy stored bows do.
