I'll address the construction of the Drifter and let others confirm velocity and shoot ability.
The Drifter, The Legend and The Shadow are the same bow. The only difference are the materials in the bow.
The Standard Drifter was made using Maple Actionwood that is dyed brown. The limbs are Maple Actionwood under Brown Glass. The tip overlays are Shedua, Back and Belly. (4 layers of Glass on the tips if I built the limbs. Making it Super string compatible.) The Older limbs built by Jim or Gordon are not super string compatible and should be used with Dacron B50 strings ONLY.
Now the question comes up: How do I know who built my bow? If the bow is marked Jim Brackenbury, Jim built the bow. If the bow is marked Jim Brackenbury Bows Inc. Gordon Porter built that bow or refinished the bow. Neither used serial numbers. With the exception of a few Jim made, but it was not consistent. If the bow is marker Brackenbury Custom Bows I made the bow. And there will be a serial number on the limb pads and riser.
I don't make The Drifter any longer because of the material change by Rutland Plywood. Actionwood is now made using Yellow Birch and in order to make that material strong enough I need to put an accent strip in the riser and that is how the Shadow is made. So I dropped the Drifter and brought back the Shadow.
The Drifter was offer in 60, 62, 64, and 66 inch lengths.
