DK 2312's would probably work for you pretty well. They will also hold up better than your 2117's. You would loose about 50 grains or so off you arrow which would bring you down to mid 8's for gpp. Couple that with swapping out your quickspins with Blazers or feathers and you will loose even more weight. With your wraps, blazers and a 125 grain tip you would be around 457 grainsTalk to Tom about it, he will give you some more ideas than I could. Just take off 25 more for the 100 grain tips you have now and you will be at 430ish. At least these are the numbers the computer is spitting at me
