fixed draws are lame. I don't understand why it became the norm other than climbers can be very lazy. i.e. very difficult to remove draws every time you're done working the "proj". i say if you leave it, shouldn't it really be "left booty"?
another pet peeve of mine is TRing on the fixed lowering/rappel point (chain, fixed carabiners, etc.). If you plan to TR, add your own slings to the anchor, then remove when rappelling. pretty easy to do and also saves the wear on fixed hardware...big time. Chain/fixed biners or quicklinks are not cheap!
