Interesting sideline, segador, do you notice that when you use the solid to split ring combo you find you get caught up on the belly hook more often when casting?
This may not happen on larger lures perhaps, but my standard islands casting rig is to use a genie clip (although now I prefer the Berkley ones) tied to my trace. I just clip lures from one lure to the next, very easy and way more solid and secure than coast locks.
Anyhow....using smaller lures like five inch or less poppers and small stick baits....up in the tropics the small wide glides from r2c are frikken lethal, I had put on a split and a solid on all my lures, makes changing the clips way easier, and I too think it gives the lures a freer action, but I found that a lot of the casts had the belly hook catching up on the clip or the trace in the cast, especially on cup face poppers, but also on the wide glides. Really annoying.
But, by clipping directly on to the eye of the lure, this stopped happening almost entirely.
Easy to do on a lure like the wide glide where the lure eye is exposed, however, on poppers, the cupped face means you cannot easily get a clip in to the eye....so there now I have to cut and uniknot each time.
I am going to get a pile of new smaller decoy split rings and solid rings today and more in a couple of weeks, hopefully smaller metal bits may stop the belly hooks from being such a pain in the bum.
Anyhow....sorry for the digression.
It is only my overwhelming natural humility that mars my perfection.
