Probably 35-45. Most in 14 lb, some I don't use anymore, but was unable to sell. A few 15 -16 lbs that I personally never used, but were given to me. I planned to sell them, but never got around to it (AMF XS Bone, Hammer 3D offset, Ebonite Cougar, Danger Zone 2).
Of the 14lbs, I probably take 3-4 on league nights, depending on which house I am in.
