I must say that I like both -- while I don't play any sort of wind instrument, I do play in sessions that sometimes include wind instruments. Pipes can be an absolute bugger due to their odd tuning -- the hornpipe with its more conventional tuning seems to me an interesting thing for a piper to add to his/her arsenal. A good piper can add a lot to a session. (Though I'd have to say that great-pipes are IMHO the thermonuclear device of sessioning )
