Needing to purchase a weed fin for 8.0-6.5 free race sails to be used on a RRD 111L Firestorm 238x68.
My options are Makani fins, MFC, Or Black Project.
Makani offers two different models and one of which is offered in carbon. MFC has been around for some time and has a rep. Black project is new and seems more high end, is also the most $'s
What do you all like of these options ?
hey man, i sail in weed conditions all the time, for the size sails your suggesting and that size board, we would probably use jp 36, maybe jp 31, the old fin works shape works well in weed as well, as far as better perfomance in terms of speed, i dont know if the fins im suggesting are the best, but good alrounders, and go through weed well, a heap of guys are using the flying objects weedsters and doing well,,, the guys posting, keef and shear tip, they definately know there weed fins and sail faster than me, they also sail shallower water, which plays a part in thier fin choice, in real conditions, not so flat, those maui deltas arent the best choice, good luck man............id just pay keef to make you one, he is the fin king!!!!!,
, ill have to agree with you about the delta's until you lift the rake, the smaller15cm to 18cm from 55 deg to 47deg, the larger you can only go 5deg to 50, with just the small change the fin will smoke to windward, and give you more pressure off the wind especially in chop 
Weeds would be loose.
Was looking at the BlackProject 42or33.6 as they give real and virtual sizing on their site.
MFC weed burner 40 or 46 (seems like a big jump)
Makani Hahalua 43
actually I must admit those floaties I've been wearing look a bit ridiculous
I'll even pickup.
I'll even pickup.
rexy had his 28-35.5 BP at canton and couldn't get going , my guess it was 38deg , I dropped it back to 42 , I haven't heard back but im guessing its better 
this fin is lifted 5deg +2cm so now a 17 at 50deg
If your looking for a weedy also give Vector Fins a choice, I have a 30 and a 40 which I use for 7.0 and 7.8 sails respectivly and on Futura 101 and 121 respectivly. Both are brilliant fins, so much fast than the Maui Ultra's they replaced.
If you are interested just contact Jesper on the Forum here or they are very quick if you email them direct as well
So, sounds like the MFC is out ?
So for heavy weed 38 degrees is bad, but for lighter weed it's better ?
Although there are lots of brands out there i could purchase the mentioned brands are the ones available at the vendors i want to give my business to. I'm sailing in the lighter floating grass spectrum.
So, Makani or Black Project. What do you think ?
Neither, If you ask 20 different people about their preference, you'll probably get 20 different answers, the common theme being that "you should buy this one because it's the one I use". Everyone's sailing style differs, so does their choice in fins. Start to see a pattern forming?
I think I can save you some money though. If you go to your local dealer and ask for a weed fin, put it around the front of your knee and try to bend it. If it bends, hand it back and try something else.
If you have a fin raked back at 45 degrees, the bend will NOT be along the flow line of the fin. Gybing will be difficult, but humorous for those watching, and recovering from the inevitable spin out will drop all of your speed.
Maui ultra fins have one of the thickest (highest) chord percentages that I've seen, choco are also fairly thick. JP make a good weedie also, but, like MFC, some of their larger models are also equipped with "can openers" at each end of the fin box.
Good luck.
I got some Maui ultra fin weedys. 24 & 28 for 7m to 4.2m. olaf who owns works there will ask what boards u ride & what sort of sailing you do & tell u what u need.
i just free ride & they sold me freestlye weedies, 45deg rake but with a cut out on the trailing edge. seem fast enough for now turn good upwind good, just need a 32ish for the 7m.
just dont stomp around when going into a gybe, nice & gental or spin out &
catch a rail splat.
hotmach im doing a post in the speed section on how to make your own fin design, its interesting c3 has a proto similar design as mine, it mite be a good idea to hang in there and see what there asking $$$$$ if your willing to unload $220+freight for a BP it mite be worth the wait, orrrrrrrrrrrrrrr wait for the D.I.Y knock a carbon one up
