We tested the 102 with our heavier riders, from 80-95+kg, using their favourite 99 as the test basis. With a few changes to the outline and bottom shape, we managed to make a board which is quicker to plane, turns easier on the wave and "feels" like a smaller board in terms of waveriding. Most of our heavy World Cup racers choose this size as their waveboard (90-95kg). Even myself as a lightweight 78kg, really enjoyed that board as a light wind waveriding machine - so the turn initiation is certainly far better than the previous board, due to thinner rails and a newer bottom shape. Especially lighter riders felt this change immediately, who were not used to such a big shape.
The Grip 86 probably has around the same planing power as a 89 Triwave in terms of that the extra thick volume in the centre lifts the board nicely out of the water, without having to have excessive width. There was a remarkable difference between the Grip 86 and the older Grip 89. In terms of waveriding, I think the Grip 86 is quite a bit better than the Tri89, just feels smaller underfoot and much more reactive. With those 2 boards in your quiver you would cover a big range and with a 5.7 and conditions you have, better than 92/82 combo. Good luck!
