I just got an OB sneaky with classic shaft. Mine was about 19 oz when it arrived. The butt was 15.5 and the shaft 3.5. It felt butt heavy to me. I took out all of the weight, and now the butt is about 15.0. The balance point is now 18". It hits stiff, and solid, but I wish the shaft was a little heavier.
Not a sneaky, but for reference, I have an OB 122 with the Classic + shaft. 19 oz total with 3.4 oz shaft and 15.6 oz butt. The balance point is 18 5/8" from butt. (not including butt cap)
