I definitely agree with CoreZero. I think the Impulse has been overlooked because of the Gamebreakers and higher end releases.
To me, the Impulse compares the most to the Hammer Phobia and Rebel. Hammer seems to have more marketing for their whole line while Columbia's marketing focus seems to be just on the high end Swerves/Tyrants
Yeah, Columbia 300 is probably the least marketed of the major brands. The Tyrant is about the most pushed ball I've seen from them in a long time... and a couple months later here comes the Gauntlet and Mako from other EBI brands so now it's back to nothing.
Ebonite isn't much better. I don't get it. The people at EBI have to know about the discrepancy, and good marketing is vital. Especially with all of the balls getting released these days.
Anyways, yeah I think the Impulse would probably be a nice step down from the Warrior Elite. The latter is a really strong ball so I wouldn't worry about too much overlap.
