Hi Koen, hmm, let's check the widths, as the Mamba's are fairly narrow with a straighter outline - so your 103 TriWave is 63.5cm wide. The Mamba 104 is 60.5cm wide. The current Grip 102 is 61cm wide. 115 FreeWave is 66cm wide. So the Mamba will for sure be more responsive on the wave than the Tri, however will probably be harder to use in the very light days. The Grip 102 however has a massive range and I used this board during our 2023 testing in Cape Town in January, along with our heavier testers - 95-100kg. Great board, plenty of float but very nice on the wave. So if anything, I would think about upgrading to that one. 2023 release is also around the corner mid September, if you are not in a rush, we may have something there you would like...:-)
