I just noticed the Browning Illusion comes with a 15# weight range on it's limbs......

One reason I could see going with the Max weight is if you are trying to duplicate the factory settings and specs. The ATA will shrink & the brace will increase when you let off of the draw weight because the cams come closer together reducing the overall distance the string must travel which in turn makes your string & drawa tad longer than it was at max ratings.

Not that this small amount should matter MUCH, but when you find yourself tryingto tune a bow that won't tune the first question you'll be asked is "do you have the bow at factory specs??" If your not pulling that maximum draw weight chances are it isn't.

One benefit I could see in buying the next higher draw weight and then backing it downis the limbs should/could last longer since they would be rated for a higher deflection/load than what you are using them at.

If I'm wrong on any of this someone please line me out in the matter - always looking to learn.
