www.1dirracing.com I have recommended them to many people on this site and a few have purchased them and couldn't be happier. They sell the G3 Power curve Reeds. with this kit you get the cage and reeds and its pretty cheap not sure what the cost is for a blaster but for a banshee it is 180.
Unbelivable power come out of these reeds your power band will start much sooner in every gear and just turns the bike into an hold on for dear life.
There are some out there that say the V-force are better but I have used almost every reed out there on some machine or another and never have I felt the power that the G3's will give you.
Good luck
