I know GYTR FWW measure their effective weight differently than Steahly does. So which one will produce a more heavier flywheel effect the GYTR 9.21 or Steahly 11oz? I have a WR450 and I'm trying to mimic the same feel on an 09YZ450 that I'm using for Eastern Enduro and Harescrambles. I generally get the heaviest FWW I can find for MX bikes that I use in the woods. Also, are there any other brands of FWW weights available other than these two?
