What do you normally do when you replace treble hooks on your baits?

On the rear treble hook I like to go up one size on my crankbaits if it doesn't affect the action of the bait.

I feel the larger rear hook gives me a better hookup.

On some of the inline spinners I may add a larger fancier bucktail treble. And a larger treble hook if possible. The more flash on the Bucktail the better. It has increased my catch. If you look at the mepps XD inline spinners they have sparkles in the Bucktail. I feel it increases the attraction. The XD3 silver/white has been a successful bait for me. I think it's the silver/sparkle.

So what changes have you made to your baits to improve them?

Thoughts??

I switch to a higher quality hook, upsize if I think I can get away with it. 

If I am changing trebles it's cause they are crap quality or beat up. It's not really for a bigger size. I also do it because I want ewg and they don't have it. I don't really fish spinner and the few I have changed now have weedless single hooks on them. I don't see the point in needing any kind of treble on those. It just limits the places you can fish it.

I don't change to much, I'll wait for the stock hooks to bend or break and then replace them with the same size, I do prefer short shank on some of my cranks and topwater lures though.
