However, typing on my MBP has become painful at times since the sport band's "tuck point" is right where my wrist rests on the MBP. Any recommendations for a strap that would be smooth at that point? I'm also considering revering the sport band to see if that helps.
Perhaps what you mean in your last sentence, but definitely try swapping the two ends of the band, that is, same side outwards, but the "top" half attached to the bottom of your watch, and the "bottom" half attached to the top of the watch. This will move the various attachment/fastening points,
possibly out of harm's way. Also give the woven nylon band a try, again with the possibility of swapping ends; may fix things for you. No need to buy one just to test, if you're near an Apple Store - just go in and ask to try on an Apple Watch that has the band, you should be able to tell pretty quick if the bits line up for you (if it works, then you can debate colors). Third, the Leather Loop - aside from the bit where it fastens, it's very smooth. Give that a try, both regular and swapped-ends. There are decent knockoffs of the Leather Loop available - I have a red one I got last year that is perhaps 75% as nice as my real black one, and was in the ballpark of $30, which is 1/5th of the real one (by no means trying to talk you out of a genuine Apple Leather Loop, just saying that if the price puts you off from possible comfort, there
are the knockoffs).
Everybody's hands and wrists are different, and the watch will fit differently. Even two people with nearly the same
sized hands might find the watch gravitating to different spots. Find what's comfortable for you. For me the watch ends up a good half inch back from the wrist bones, so I don't hit any of the "accidental button press" problems some find. I've been lucky in having all the bands be comfortable. The only one that gives me trouble typing (on an MBP, like you) is (a knockoff of the) Milanese Loop - metal on the metal keyboard is no good.
