I would certainly agree with ordering them longer. Even 2 or 3 inches longer. It's easier to cut 'em down than to extend 'em back. They'll play a little stiffer cut down, but since you're experimenting, you may want to leave yourself some room to play. Or, if you're ordering more than one club, get them built to different lengths, and see what you like best. Then adjust the other clubs to suit.
