How? Is it the more let-off greater the speed loss? What would be the difference between 65 and 85% on my 70# (d/w) Slayer,.. let say shooting 300 fps with 85% let-of as of now?

The greater the let off the greater the loss of speed...but don't get all worked up it is only about a 4-6fps loss or gain (depending which way you go).
Most folks are only concerned with let off because of the way it feels or holds not because of a loss or gain in speed.

Thanks scepterman30x for the explanation!! :)
4 0r 5 fps?,... then I'm not worry about it. My Slayer is shooting 305fps with 85% let- off and that's more than I need. :cool:

There are other benefits too less letoff to.

It is less of a change in DW from valley to peak, so the draw cycle is smoother, and the accelleration as the bow shoots is smoother too. It also makes it easier to hold well at the wall at lower draw weights. Makes it a bit easier to shoot more accurately. In fact, the only advantage to high letoff (75%-85%) is being able to hold on a game animal till the best offortunity for a shot presents itself, which could be a bit longer than you would expect from the time you draw. EG. I'd draw on a deer when it faces away from me so it wouldn't see me. however, I'd have to wait till it turned before I could shoot this could be a while.

How do you change the let off on the m-pro cam??

Lengthen the DL, and shorten the draw stop.

Actually i meant the older m-pro cam, like the ones on the 2007 bowline:p

I think you buy a module with a slash on it. For example, order the F-7/ instead of the F-7. I could be wrong; I just remember it on a spec sheet somewhere. Could have been for the Dynacam, but I think they use the same mods.

You are correct.

only other thing that is pertinant is state law some states only allow 65% let off

Not arguing, but name some. I like to know these things.
