YES indeed! SR is correct on the kite! And I understand John's point, as I've flown with him before! The SUL is very nice as a solo flyer, if you need something that flies in really light winds, but doesn't put quite as big a dent in your pocket as a Zen! In solo flying, you don't need to carry as much momentum through maneuvers as you do in team flying! A std, with the correct frame, in the hands of a good flier, will fly in almost the same wind ranges as an SUL!! And that's why I have one, an SUL that is, I'm not as good - YET!!
Matt - don't be tempted to buy and use too strong a frame in your std, you'll risk stretching out the sail! Reason for getting another!!
