Okay, so the regular 110 is *not* a suspending bait. It's supposed to be a slow-float. They also make a medium-float (110 silent riser, not the same thing as a 110 silent) and a high-float version. Neither of which seem to be very popular, but that's all right with me
If you want a *suspending* 110, you need an 110SP (may or may not be a JDM-only version), or an 110FX. The latter is easier to acquire in the US.
Also, this whole discussion about "best suspending jerkbait" is kinda vague without knowing what diving depth and bait size the OP is looking for.
Going from shallow to deep, here are some *suspending* baits I like:
Flashminnow, 110 Magnum (there's a suspending version, and a floating version), World Minnow, Slender Pointer, Pointer, 110 plus 1, KVD deep jerkbait, Staysee v2 (there are three versions of the Staysee, v2 is the suspending one).
And that list contains probably less than a fifth of the different jerkbait types/ models I have. Yes, I love jerkbaits. I also love details.
If I had to pick only two, I'll take a 112MR Slender Pointer for shallow, and a made in Japan 110 plus 1 for deeper work. I feel the older made in Japan 110 plus 1's are a hair lighter (although I suppose that depends on the color) and you can tune them with slightly lighter/ heavier split ring(s) for warm vs cold water. The box will say the country of origin (Japan or Malaysia, I think I've seen a few made in Vietnam too).
