The 10"is that top dog for me in the tt line up, followed up by the 8". The 10" has a ton of drawing power, I have caught two fish at once on that bait. I fish them mostly in the summer months.
If you haven't seen Southern Trout Eaters, you should pick up a copy, it has a lot of good information that I found really helpful when I started getting into bigger baits. You can find it at southerntrouteaters or tw.
