If I'm fishing a lake for LMB that has lots of SMB in it, what bait will catch them both the best? 

I've caught them both on a Senko, I've caught them both on a Fat Ika.  Have you guys found other baits that work better for BOTH fish?

Jerkbaits...Specifically the XR-08 when they

are very active, Pointer 100 the rest of the

time. Another is a 3 1/2" tube.

tube

Thanks guys, I'll let you know how it works out if I ever get to fish again.  This snow is sucking the life right out of me.

The Cabin Creek Critter Gitter 4" tube in Junebug has landed me quite a few big green bass while after smallies.  Next though, would be the X-Rap 8 like RW said.  Caught some darn nice hybrid stripers on the X-Rap 8 as well.

14 inch castaic trout swimbait gets em every time....

swim jig

Like GMAN and RW said..........

TUBE

I rig my Fat Ika's backwards, as I learned from RW.

I know the Fat Ika isn't a tube, but do you all rig any tubes backwards like you can with the Ika?  Are you usually fishing the tubes weightless or T-Rigged/C-rigged?

In StClair it's the spinnerbait

Tubes, rapala subwalk, Jitterbugs, berkley hollowbelly swimbaits, spinnerbait white/chart

Can't beat tubes.

jig and pig trailer

Crankbaits, spinnerbaits, Jerkbaits, all pull double duty for me. This season come Hell or high water, I'm going to catch some smallies on a tube.

Swimming a 5" Kalin grub on pea gravel banks gets pre-spawn Spots, Largies, and Smallmouths for me on Table Rock and Beaver.

Equal opportunity fish-getter. ;D

I have seen no real differences as to which specie of Bass will hit my baits, if presented correctly.

Yeah, I catch more LMs on frogs and rats, but other than that and really BIG swimbaits, I find both species hit my lures, be it tubes, jerks, Senkos, Flukes, grubs on ballhead jigheads, cranks, topwaters, drop-shot, spinnerbaits, etc.
