I usually lend on top, then go for the top left lemon first by jumping in his "niche" from below. More often then not he takes out the top right lemon right away, and a few of the lower ones, too. Then I go back up and around and re-enter the lemon gauntlet from the right side. I don't use the teleporter at all unless the first lemon gives me a hard time with an unavoidable missile.
Of course, one day I'll find a way to get a big crystal on this level in time...
