I feel exactly the same way. I started out playing 3 cushion in the 90's and still shoot with the same old carom cue I bought back then, even though I play pool pretty much exclusively these days. As to what I find different: I'm dead certain it deflects much less than even "low deflection shafts", carom balls being ~20% heavier than pool balls. I suppose that's at least partly why carom cues have a noticeably more obtuse taper, and I can definitely feel the shaft on any pool cue rattling after a medium to hard shot whenever I do grab one. More recently I have noticed there are certain shots where the slightly shorter cue affects my stroke, like when I have to use a longer bridge with lots of follow thru; frankly, it's small potatoes and probably has more to do with the fundamentals than the cue itself. In the end I find I play better with it and am pretty sure it's not because it's "superior" to any other, but because it's what I'm used to playing with.
