I throw the same weight equipment at everything. All of the balls I own are 16lb. I use a red/black/white swirl Ebonite Maxim for all of my 4, 6, 7 and 10 pin single spares or combination of those pins. I also throw it at the baby split (3-10). I throw my strike ball at everything else. I use the same release with my spare ball, except for the fact that I don't "hit" it at the bottom of my release. I used to flatten my wrist, but I was way too inconsistent. I feel that my spare game has improved tremendously recently and a few people on here can attest to that.
