Bill, what happens to the size of the block at 550? I went to darts site and here is the race block specs...you can get 455 with this. Do you use the aluminum block to get 500 or is this a totally new block? Must be...HOw big is the bore on these new blokcs? I can see some advantages to this, lighter, power to weight etc. Anyway disavantages with the newer blocks?

BBC have to go to these much taller decks to get it, 11.1 deck...any new blocks for the BBC coming out to keep up with the "small motor"
