I disagree with seeing virtually all flops in heads-up limit play - I don't think it's a winning play.
Playing heads-up limit is so volatile and so high variance, that I wouldn't recommend anyone do it unless you're looking specifically for the challenge of learning how to (which is definitely a good reason, however). But one bad beat and you will have a lot of small pots to win to make up for it.
Styro - and I mean no offense by this - but although there's a good chance you were the better player of the two of you, maybe even by far, I think you'd be wise to attribute a large part of your winnings to shortterm luck. I say this with the best of intentions; looking to a good run as indicative of how you "should" win can be very dangerous psychologically. Be careful, friend.
