Years ago, I attended a 3D tournament and a Hoyt factory rep. was there. I was shooting a provantage with recurve style limbs at the time. Originally the bow was adjustable between 60 and 80 lbs. I had the bow on the scale and it would not go to 80 lbs fully cranked. I asked the rep. how I could get 80, and he just gave my higher "limb blocks". These act as a fulcrum, and were loacted behind the adjustment bolt. Basically it allowed greater adjustment range and more stress to be put on the limbs. When fully cranked it was at 92 lbs. I shot it at 90 for about a year, no problems.

I have no idea if a similar thig can be done with your bow, but it may be worth looking into.

There is another way to increase draw weight, and that is to intall a longer string. Of course that means a longer draw length. That may or may not work for you.
