Really nice day testing the 63 wide mXr prototype. Wanted to get to know this board and what it was capable of so where others went out with their speed gear I was on a colossus compared to those boards. First I qwent out with Black Diamond Fins M25 and it was actually quite good, even though I was one of the first ou as the wind had to come in still. Top speeds were in 65-68 kmh range. Moved up to S1 28 and eventually S1 30, which I found to be the best of the 3. All with 7.0 sail. It was good fun and I am curious where I will end up between the speed boarkds with my average. We really learneed a lot again today!
