existing trebles hooks on cranks, topwaters, etc?  Just wondering if this was ok to do.

generally i think it is fine but make sure that they are not too large or they will get tangled with each other and be an overall headache.  thats my opinion anyways

Though I believe that Gamakatsu makes the best worm hooks, I prefer these on hardbaits.

I agree with Dan, they are fantastic.

Falcon

I agree with all three of the other DUDES.

I generally use Daiitchi 4x trebles, but will spend the money on Gammy ewg's on some of my shallow runners; ewg's are more weedless.

I didn't think about them being a little more weedless---thanks
