I have had alot more luck out of the carbon fiber reeds.I put the stocks in with boyesen replacements just made my motor super rich.  They weren't stiff enough for my set up. But those new super stockers that boyesen make for the stock cage look like they would work good also since their carbon fiber.I was thinking about trying them out myself. But all you can do is try fmf out and see what they do. Might be able to put the boyesen pro reed on the fmf cage just doing some trimming on them.It might work real well then.It does have some big flow holes in it.
