I've been watching this thread for a few days now and am fairly suprised by some of the replys! I have flown the 08's an 09's for somewhere in the region of 100 hours maybe more maybe less and to be honest theres barely any difference between them, both are great kites, lay an 09 on top of an 08 and the 09 has a very small (couple of inches difference in canopy depth) difference,the struts on the 09's have been moved.To fly the 09's do feel very very marginally smoother as to whether they make more power anywhere is arguable.Compared to the 07s either the 08's or 09s turn much faster and also do not have the tendancy to back stall that the 07s had when oversheeted on the up stroke.I would personally buy either the 08s or 09s purely on which was being offered for the best price,I would give the 07s a miss as the improvements from 08 are substantial.
