I'd have to ask if the bow/arrow combination was tuned prior to switching releases. If so then increasing the draw and inch will necessitate retuning--probably dropping the poundage for starters. If it was not tuned or you don't know how to tune then you need to get a copy of Easton's Tuning Guide and get to it. You can find it at www.huntersfriend.com. Follow this and learn what tuning is about and I'll bet the wobble would go away.

You should probably be shooting a 300 spine (stiffer), but dropping the poundage can accomplish the same thing without spending money on new shafts. The limb boltsare on a bow for a reason. Don't get caught up in the idea they have to be bottomed out. When tuning adjust them, along with centershot and nocking point height and let things fall where they may. Mkae it weasy on yourself and don't try to overthink everything.

As to whether your cam is hard is medium or soft? You can hardly ever go wrong by assuming it is hard. Even if your arrowes are spined on the stiff side it's a lot easier to tune than it is with underspined arrows. This is especially true if shooting broadheads. With field points you can get half decent flight and not see a lot of the wobble you might be seeing now. Put those little blades on the front and a little wobble can become a big wobble with inconsistent flight.
