I am pleased to report that they preformed extremely well, fast, early planing and great on the wave. In fact I'm so impressed with the setup I've ordered 15 centres for the 87. For onshore I'm going to try 17cm scorchers and run the board as a twinser . If this works well I can also use the 16's on the 87 cube as a twinser in onshore conditions.
If the 106 cube needs a bit more zip on light wind days I'll swap the 8cm sides for 9cm , this should be enough extra lift for marginal 5.7 days. Watch this space as I'm extremely curious as to how my cubes will preform as twinsers.
cheers Rob

Hi Robo. Just wondering, what was wrong with the stock MFC fins that come with the board ? I have the previous model Cube in the 86L and I find it goes like a dream with the stock fins with sails from 5.3 down to 4.2.
I've heard good things about the K4 scorchers so I would love to know how they perform compaired to the stock fins. Cheers.
Hi Stonny, I never really had a problem with the stock MFC fins supplied with the boards. Although usually when putting a big sail like a 5.7 on my 106 or old 105 slightly bigger thruster fins than the supplied ones helped. However, they are a older design , and interestingly I noticed some sponsored sailors were switching to the MFC K300 quad setup instead of the supplied stock MFC's. In a visual and handling comparison with the K300's and K4 scorchers appear to be very similar to each other. On the water they both sail extremely well, fast, early to release , good grip and turn well. I would say both out preform the stock fins , by how much is hard to say. The main advantage with the K4's is the price, if you grind out any MFC fins on a rocky shore or hit something in the water (happens most people from time to time) replacing them is not cheap , and you probably could buy 3 K4 sets for 1 MFC set. Anyone I know who has switched to either the K300's or a K4 setup generally don't go back to the stock fins.
On another note, I've been sailing my 106 as a twinser in onshore conditions a lot recently. I have to say I really like how the board handles. A bit quicker off the beach and has a slippery feel which is a lot of fun in messier conditions.
I will get around to trying the 87 as a twinser but every time I sailed it the conditions were seriously nuking and I felt I needed the thrusters for a bit extra control.
