I pour the Darter 570/575...that head is pretty pointed, and looking at the Bullet head, the Darter seems to be more finely-pointed than the Bullet, so the Darter would probably lend a very slight improvement to erratic action...BUT, when You'll be using paddle/swim-tailed and curly-tailed baits, that tail's resistance is going to "take over" and it won't matter much what 'head You use. Using straight-tailed baits, the 'head will make a bigger difference...say between the Round head and the Darter, You'll notice a difference in action. A jighead rigged with a plastic that has a swim/paddle/curl tail with be controlled by the tail...the resistance is at the rear...similar scenario when You take a "darting" TopWater Bait and put a "prop" on the rear, it's ability to really dart/zig-zag is greatly reduced.
I'd go with the Darter, as it won't matter much with a swim-tailed bait, but when You rig a straight-tailed bait onto that Head, now that bait looks like it's been hanging out in the Coffee Pot District. The Darter will serve double-duty here.
Read the OP (Original Post). The Erie is my #1 'head, with the Darter in 2nd place...
