I don't see that "problem" around here anymore. On the contrary, there are now very good waveboards for our regular conditions. The EVO range started out like that and has changed the mind set of many. A bit of wishful thinking though can happen to anybody, as the smaller gear is more fun to sail. Try a 60 liter board the next time you get bounced about on a windy day, and you'll see why they are so nice in the right conditions.
Another trend setter was the Hypersonic, when slalom in general had become too complicated, with very narrow range boards, and people were lossing interest. Starboard came with a board that have the widest wind range I've ever seen from one board, and that reignited the sport and there are now very good slalom boards for lightwind days too.
