For now I think the heads will be released in the weights previously listed, due to current material and process limitations. VPA wants a well built 2 blade option made available for a reasonable price. At this point producing heads approaching a 3:1 ratio would push the price well beyond what most would be willing to pay, thus a compromise in design seems necessary.
If someone wants a specific head design made available it can be created on a custom basis, however the cost of a special built head would blow most guy's mind, not to mention their pocketbooks. I know it would mine:^(
My personal choice will be the 250 grain since I've been shooting 250 gr. 3-blade Terminators well out of my 60 pound Tall Tines recurve. My total arrow weight is approx. 600 gr. I also prefer the longer profile of the 250.
VPA is at least making an effort to produce a head that should fill the requirements of a number of archers who don't want to pay over-the-top prices just to "experiment" with a 2 blade head. One of the things that makes this sport so interesting is all of the choices we have and make on the road to "personal satisfaction". To each his own!
