I agree with most of what you've said and it describes my reading pretty well, too. I like being convinced of pairings...of course the problem is that so much fic is written for shippers, so there's no convincing going on (so rare pairings are actually better that way, since they do have to convince people).

The only time I have been OTPish is with Louis and Lestat from Vampire Chronicles, but even then I liked fic with them with others so long as it fit in the canon timeline (like Louis/Armand during the years Louis thought Lestat was dead).
