It's easier to tune the bow to the arrow than the other way around if you're close.
Move your nock point up just a hair.
If you're weak you don't want heavier you want a lighter point, but the easiest thing to do is use a slightly thicker side plate, or build your existing side plate out by placing a tooth pick or match under it. Doing so will decrease the amount of spine you need for your bow to be tuned.
Very easy to do all that and best of all you don't have to spend any money to do it. You could also shorten your arrows a smidge if you have clearance.
Hope this helps, Tim
