no its not the foil is different.. the k2.1's are flat foiled the mayhem are 80/20Quote:

Yes indeed, my "fail"! I just checked mine and they are 80/20 and so are the Q1000s that came with the flat foiled GAM front fins too.Quote:

no i didn't i have the thruster k2.1s and bought the mayhem quad set for my spud and used the rears with my k fronts on my dom with the lil nubster.. i tried getting my hands on the k rears but couldn't find anyone just selling the rears and didn't want to buy the whole quad set..Quote:

The first is the "slug" after some refinement, yet to be tested. The second and third currently being tested. I'll update with some comparative results later - once I work it out!
Some R&D there slow man, keep us posted
I have the flat k2.1 quad rears. Kelly actually uses different ones to his sig set and I believe that is because he prefers the 80/20 foil.
I can't remember the difference but I did read somewhere on surfermag forum what the effect the foil difference had.
80/20 helps get board on rail easier
Attachment 187
OK I've done a lot more testing and the last one seems to be the most effective, for what I want. The closer the trailing edge is to perpendicular (steeper angle) the more pivotal and direct feel it gives to the board. They all help with speed and drive but I reasoned that if I moved the highest point further forward it would make the board looser but still pivot in the same way. This didn't really happen, what happened was the slacker the angle of the trailing edge the more vague and less pivotal and direct the board felt. The only reason the "slug" worked so well originally was that it had a steep trailing edge, when it looked closer to just a sawn off GX. Once I refined the slug to eliminate the stark on/off feel in bouncy chop, it lost its direct and pivotal feel, pretty much a failure for my purposes - though it may have application elsewhere.
I think the MR TX trailer is an ideal fin to start with to make this kind of fin as it is narrower which I feel also helps with speed and unwanted drag and makes it easier to shape and foil. The thicker fins I tried like the GX and a G-YU (though these were slug versions) seemed to add some drag and cavitation though I'm not really sure, since they just weren't delivering what I wanted I stopped experimenting with them. In fact the G-YU was a much bigger slug (45mm deep) but I've since refoiled it to look more like last one above although its trailing edge doesn't finish as far back and since its height (depth) was greatly reduced it's more or less on the scrap heap. Same for the 2nd one above it has more pivot but not as much as the last and was also a little vague.
So in summary my findings are that if you want more direction and pivot you want a slack angled leading edge curve with the highest point towards the back with a steep trailing edge. The trailing edge finishes about 1/2" behind the last FCS plug (I don't know how that relates to a futures fin box) and the highest point (or depth) is just over 1" with a base of about 3 1/2" (90mm see http://www.finshop.com.au/Products?P...67&cmd=Display) just like the last one above.

Fritz, it's pictured a couple of posts above (also in the attachment 187 in the roundup post above), it is the last fin of the the 3. If you want a bigger picture of it, I'll put one up later, let me know.Quote:
