I hunted with the Sweetland Forgewwods for years, starting in the late 1950's, and shot a lot of big game with them. I also used the Alaskan forgewoods for a few years.
Best wood shaft I've every used was the original Sweetland Forgewoods ... followed by the Alaskan Forgewoods.
One reason the performed so well for me (which took me years to realize) was that, with the 190 Grizzly on top they just edge into the EFOC range; just over 19%. That was because of the differential compression at the shaft's front and rear. The front is (was) compressd at a 3:1 ratio, the rear at 1.6:1 ratio. In effect this created a 'one piece self footed' wood arrow; denser and heavier at the shaft's front than at the shaft's rear.
