Should I buy a Spyder Pilot or a Tippmann Carver One Paintball Gun?

Depends on your style of play. If you like speedball more, you'll want the Pilot. If you like woodsball exclusively, you might like the Carver One more. Keep in mind the Pilot is electronic, so it shoots faster, but that also means it's best used with an electronic hopper, and that can increase your initial investment.
