Eddie, I think we're thinking much the same thing....just maybe not eye to eye on the percentages.
MY thoughts are that the percentages would be more along the lines of 65/35 (shaft/butt) regarding "hit and playability". Everyone knows that the shaft is very, very important, but I don't think the butt's role is that small. Despite being a counterbalance and transferring the initial feedback, there is a quite a bit more going on imo that just in the forearm and joint area of the butt. My thoughts are that for a cue to feel "right" for the player, it has to have the correct resonance and sound all the way back through your grip hand, the entire length of the cue (what feels and sounds right for a given player).
I also use to agree that a bunch of inlays and such would "take away from the hit" but after several years of trying out literally hundreds of cues, I'm not so sure now.....sure it can, but generally 1/8" deep inlays just aren't going to have much affect on the overall hit. Now I'm more of a believer that hit is more dependent on how everything comes together [rock-solid central core throughout the butt construction....little to no "slop"....tight splice (if present)....nice snug joint connection....tight rings....balance....quality materials (wood, adhesives, etc.)....and naturally the shaft, ferrule, and tip].
Have hit with some of the most fancy cues you could believe that played absolutely lights-out....and then turned around and tried the same superb shaft on another butt with somewhat dissimilar results. IMO cues perform best when the shaft is specifically made to match up to the butt. Never really bought into the screw-on Predator concept. Even gave them a try, and although the science and logic makes perfect sense enough, they just never felt right to me.
Just a few rambling thougths. Sure some others might agree and disagree with these points. :smile-square:
