I was thinking in the 6-10" range,so far I haven't been able to find anyone around that has trout but I haven't tried real hard as I'm not planning until Feb or March. Can't say I'm too impressed with the fish farm guys here in the KC area. If they don't have what I'm looking for, they always tell me it's a stupid idea, will never work or a waste of money and recommend using fatheads (which they have). The last guy was trying to tell me, the bass will never eat a trout in the 6-10 inch range. Most of my bass range 2-3 pounds with a handful of 4-5 pounders and one 8 pounder. I saw the 8 pounder suck down an 10-12" Gizzard shad (skinny though) like it was just eating a worm.
