I like the AD Trads and the AD Hammerhead Trads (along with the Lite versions of both of these). They are very forgiving of point weight and draw weight. I have bumped the weight of the arrows plus points up to 915 grains without any problem. The Carbon Express shafts are nice too, but not as forgiving as the AD shafts. There are all sorts of combinations of shafts, inserts, and points you could put together to end up with finished arrows in the 650 grain range. If I were you I would probably start with Hammerhead Lites and 100 grain brass inserts and go from there. You should be able to easily get the arrow weight you want and would end up with a super tough shaft that would work well at your bow's draw weight.
