When in doubt, go the next step higher in spine. Especially with Goldtips, from what I hear thier chart sucks. Most charts blow actually, they just don't have enough information to be accurate. One of the arrow selection programs currently on the market work much better.

I'm sure some people here have it, maybe someone could run the numbers for your bow and see what comes up. You can get trial versions of them as well. I had two of them and want to buy one, but just can't afford it now. Besides I found the arrows I wanted. The only reason to purchase it would be to help other poeple.

I commend your thinking on arrow weight, most don't think that way any more. However what you have would mostly work and would even be safe up to 70 lbs unless you shoot an extremely fast bow something. As long as the spine is correct for your draw length and weight.

Keep in mind the charts you are looking at do not take into a acount for using an overdraw, which you are. I say regardless of how far back your rest sets, use the correct length arrows for your set up. The correct length is between an inch shorter than your draw length, and the the same length as your draw length. If you are shooting arrows 2 inches shorter than your draw length you are shooting an overdraw and need to take that into consideration when picking an arrow.
