Here's a little tub test swim footage of the 5.5" Crusher Gill crank down. Note that this is with about 1.5ft of line out and not a true representation of the action on a full cast. I designed the Crusher Gill to dive down quickly and stall/suspend before slowly floating up to the surface. A tight joint and relatively flat-sided profile gives me confidence to fish it in colder water than I would a traditional crankdown with a wider joint and body. It digs down head first to better deflect off of cover, and the thumping swim can be felt all the way up your arm.
