Thanks again for all the responses and inputs.
A bit of an update now that I've had a month practice driving manual: I've gotten to the point when I can almost shift without thinking about it, and the timing of letting the revs drop for upshifts have almost become second nature.
The only shift that's really rough for me is the shift from 1st to 2nd, but it's good to see I'm not the only one with that problem. I almost have to feather the clutch into 2nd lighter than I do going into 1st. Hopefully this isn't putting too much wear on the clutch but I figure I'd rather wear the clutch than the transmission.
