May sound strange but I often swap out the treble on a small lure for a #10 single. Works on a 0 Mepps without a skirt or two on a tiny Rapala mid water sinker.
They are harder to find but you can get hooks designed for that, to use on lures instead of trebles. Makes catch and release much easier on all fish. They have a design fit for the task and wider eyes etc...
These for instance
That said I use a size 8 straight shank hook and have never had issues with trout. One thing I have noticed that helps me out is I cover the hook and form a ball with the power bait, then I slightly push the hook tip out, squeeze the bait ball near the eye of the hook and make a few twisting motions slightly twisting the top of the bait ball up the eye and line a bit..now it is more like a tear drop shape and well secure with just a small point of the hook out for quick hook ups.
Incidentally this is the same method I use for dough balls for carp when fishing floats or chasing very finicky fish. The method can also be helpful when surface fishing bread. You pierce the bread through with the hook, turn the hook and bring it back securing the bread. Then for added strength pinch the bit near the eye and give it the same twist or two to lock it in.
I know that is a bit late in response but hopefully it helps for the future!
