Well, Grandpa, I don't know if my experience is sufficient. I'm just a beginner at this. Started fishing springers in 1985, and got 28 fish to the boat last year. What do I know, I'm just a commie punk. ;\)

In my experience, it's about a wash between trebles and siwashes. The jury is out on the 510's. I think trebles connect with more fish, but I think I lose more during the fight. Siwashes seem to lose a few more (maybe 5 to 10%) on the initial strike, but once they're on, that fish is dinner. Siwashes are lots easier to get loose from the fish and the net.

I for one do not worry about running a plug with siwashes. I seem to miss about 20-30% of the strikes with either hook type. The 510's have not yet proven that they improve on that. The 510's are new to my boat. Thus far, they are 1 for 2, and the lost fish could well have been my error.

I should add, more than 3/4 of my plugs have singles on them.
