They pulled like trucks, in a good way that is
One of the guys had a 7.5 and 9.5m2 AR5 for many years, after they were replaced (when we had very high end C kites the next 5 years) and his 7.5 was used when we were on 9 and 10m2, and the 9.5 used when we were all on 12 or even 13m2, so they got massive power compared to newer C kites, although they have got a bit more grunt now too
I had the AR5 5.5 and 9.5, awesome kites back then.
I remember later having the 11.5 we could go in almost "nothing" on the surfboards, and some had the 13.5 which was a pure light wind machine - so the 15.5 must have been a pull truck ?

Always think about them as "the good old days" - but maybe not, if used today, or ?
Let us hear what you will experience Bille
