i've never tried a bio, but i want to. i'll try it in the baker backcountry so now worries of wrecking myself. gimme some tips. what i should look out for. what i should definately not do. how huge should i be going (keep in mind that i don't know how to do them). how many rotations should i try for my first one. how long did it take you before you waxed your first.
