Man, 268 is plenty good. I shoot 268 also, and i have NO problems whatsoever. 3D, hunting, anything. I mean, i could see why youd be pissed about what the guy said, but i wouldlnt worry about your speed at all. If anything, put some leaches in there, a fletcher tru peep, and a soft nock with 2 bumbers underneath, and you might gain some speed.
