shortened rope to learn w2w moves?

[whatafall]

So tired of landing in the middle, I took the rope up a bit and can now clear wake to wake easily when the boat is planing. While the wake is smaller, the gap is narrower so I get to land on the 'downramp' every pass. Jumped back and forth for awhile, then got my w2w 180's going as easily as I had done them into the middle before.

Question#1: is this 'cheating,' bad form, or undesirable in some way?
Seems like a great ego-boost and knee saver for beginners.

(Can't seem to hold the right speed from my In/Out board so this also gives me a consitant wake - other ways?)
