I rode a fair bit of slush this year soon discovered that carving hard = edge sinking = fail. Depending on the slushiness you'll probably need to do skidded turns. With mounds of mini slush moguls you'll need to be quite dynamic. Someone with more knowledge will probably enlighten you. If it gets too tiring just bomb straight over a few moguls picking up a fair bit of speed come to a stop rinse repeat
. Also second that suspension anology. Worked for me. Just keep real loose and flexed and feel like your legs dont weigh anything if that makes any sense ha.
Ignore this and look above =)
