I've been using Spro baits for the past 5 or 6 years, starting with their Bronzeye frog way back in the day when it first came out (best frog on the market i might add). I've been using the Little John and Little John MD for a couple years and love both of them. Haven't tried the Big Un yet, that huge deep diver Little John as I already have enough DT16's and DD22's. That little squarebill computer chip lip on the Little John works great, haven't had any chipping or breaking at all, and I grind em into the bottom too. As far as their swimbaits go, I love the little guy. That 4 inch sized on, with the 1 hook in the belly, just doesn't do it for me like the Tru Tungsten 4 inch swimmer does. I miss/lose a lot of fish that hit that bait due to that fact. The little guy works great though, it really looks like those little "no see um" bait fish that skim along the surface while bass are schooling. I've caught white perch, largemouth, spots, and little stripers on it already, haven't had any durability issues at all. It IS a little light, so spinning tackle is probably going to be easier to use than casting. Hope this helps, I LOVE Spro's products. But thats just me.
