I'm primarily a smallmouth angler river fishing out of a kayak. Recently I made the decision to try and ditch trebles and replace them with single inline hooks for my poppers. I mainly use a megabass popx and switched from the trebles to a size #1 Owner inline replacement hook. I feel like for the most part that the action is unchanged. The only exception to this is when I go to walk the bait quickly, the bait seems like it's more likely to dig down into the water instead of on top. Wondering if I should drop down a size on the front to keep more weight on the rear, but a #2 hook is pretty small. Hoping someone has some tips.

could you get a small scale and compare the weights of the single vrs treble hooks?

^ just in case you haven't got it already...aside from that pulling up the lure on basspro's website helps (for me) as they usually give you the hook size. I normally like to use this chart as a starting point and then for some lures I like a slightly larger single hook which seems to be what you've gone with...and to be honest the 2/0 and #1s are pretty much what I use. In this case that lure looks like a size 6 so it might be worth going down to a #2 for the front hook (or both). I did order some of those a while back and can confirm it is a noticeable difference between the #2 and 1 so maybe pick up a small pack and see if that helps at all...haven't seen this happen but that said I generally stick to 1/2oz  - 3/4oz lures and the lightest I've gone down to (and used the #2s for) was a shad rap 6 which seemed to do ok for me...good luck.
