I've used the 1 1/8" 190 glue on VPA and like it a lot, enuf to carry them in stock, but would like a wider one, too. Consider tho, that the VPA's are machined from a single piece of steel. If they go up in diameter, they have to start with larger stock which COSTS more and there is gonna be a lot more waste. At $10+ each, they are already in the premium price range and many of us aren't yet ready to pay that for broadheads. They are worth it to me, but I'm probably not gonna buy a dozen. I am gonna try some 250's, tho.
