mine (even though it was the password version) felt just about the same as stock, and maybe even a little taller than stock.Adding weight essentially makes you use more force to increase the momentum of the knob, which makes shifting smoother. But, different strokes for different folks. I went from TWM's Type R, back to Stock Si, to Spoon Ti.
I actually like the Spoon Ti more now, it felt really weird when I first put it on, very notchy. But now, it's feels just as smooth as stock to me, and I like the lighter weight when I drive faster.
Heavy knobs feel awesome when I'm "cruising", but stock or lighter feels even better when shifting more often. Might be just me though.
