personally i think the trick for practice is to skip the line length just *below* your mid loop. So if you have a -30 loop you ski up the rope thus: -22, -30, -32 etc. if you're using a 33.5 loop you ski -22, -28, -33.5, -35. that way you aren't skiing an extra loop, you're just making the pass before your ' wanna make ' a bit tougher, which makes your ' wanna make ' a much smaller step up.
