The speed, timmy, DM4, etc all shoot faster than a halo can feed, so it really doesnt matter which one is faster. The timmy and angel both have the same method of operation, so there is almost no difference in the way it shoots (ball path etc) The timmy used to be a bit more accurate because of less recoil though its low pressure operation. Then, WDP took the hint and came out with the new speed engine which dropped the pressure of the angel to timmy levels. So basically if you can tell that one gun is more better than the other, go for it. The Speed and the Timmy work the same, act the same, shoot the same. There.
