but sliding is apparently terrible for your hands so ... pianoing?
Sliding does hurt your hands more and it's worse if they are dry. If you have a glove or they're sweaty it's easier but you're still rubbing your fingers against some hard surface at a high speed. Pianoing is harder at first and it gets easier with practice but it can also lead to a stiff hand after some hours of practice.
Whatever you guys do, take good care of your hands. Arm, wrist, hand and finger stretching exercises and breaks should be a part of your regular gaming habits. Most importantly, having self control and not mashing the buttons. You don't want to get to almost 40 trying to do some sliding/piano/both combos for a while and realize your fingers/hands are starting to hurt. Stretching/breaks/control also helps if you work a lot typing on a pc keyboard and/or play some instrument. You need two or there different pianoing/slinding/both techniques so your hands don't get tired of doing only one thing which becomes evident when you practice them and after a while of doing one method you switch to another and suddenly it's easier for you(and your hands) to do it. You also need to restrain yourself A LOT so you do the smallest amount of pushing per button press, hurting your hands the least(or not hurting them at all). Stress/pressure also gets to your hands if you're in a tourney or moneymatch.
