Once hooked up, I'd say about 85% or so. I'd guess my success rate on the hookset to be somewhat lower, maybe 65% or so?

I have no possible idea how this would be accurately calculated unless documenting every bass encounter starting now, which would be an insane burden. I'll just say that I land the vast majority of bass hooked by a single hook and I lose probably 1/4 of treble hooked bass.

I'd say for me it's 90% land ratio. Most often if I lose one it's on a crankbait, but I fish crankbaits a lot too.

My hookset ratio has been really good but I've recently started using a new rod and my ratio is down to 2 for 10.

 

What heartbreak. This rod us my longest and slowest .  Changing my hookset  has given me the fits. I lost a 20" smallie on the jump, I ripped his lip whaling back on the line while he was head shaking.
