[llCanibusll]

im buying a preadator implulse and i was wondering is there anything i should look out for and pros/cons about the gun or any upgrades i should get for besides the obvious ones! and last what is an undertow bolt and how is it diferent from the 3 hole bolt.
thanks,
rich

the undertow bolt puts a tad of backspin on the ball, and tightens the shot grouping at distances;)

[llCanibusll]

is it superior to the 3 hole?

very much so
