For a stock, bolt on blaster or even a mild built blaster toomeys do great.
However, once you start to get serious with mods it falls off and the power pros pipe ( also named f7, ct ) really shines.
So it really depends, is your blaster mild? - toomey.... or do you plan on going all out? F7....
The nice thing about the F7 is it will grow with your mods so it can save you money.
