Gateway makes feathers that are 1 7/8", 2", 2 1/4", and 3". They sell them at Lancaster Archery. You can even use them in foul weather too ;).

Gateway makes a feather called the rayzr broadhead feather. They are 2" long and weight 1.7 grains a piece. Here is a picture of some that I made up.

RE: weight of feathers?
 

cool, does a feather that short handle broadheads very good? I shoot carbon express 300's 27.5 inches long with a 100 grain razorcap broadheads. Do you think one of those short feathers would be able to steer that broadhead good?
