Flaperons to Elevator mixing.
I just got my Sig Somethin' Extra back together from its last run in with a tree and I now have a computer radio. I can't wait to try this thing out with flaperons, there will probably be butterflies passing it up! 
Anyway another mix I put in it was flaps to elevator, which way do I want these to move? When I pull back on my stick the elevator goes up and the ailerons go down (more lift)? I would think that would be it so the wings go up and the elevator goes down, is that right? Anyone ever fly the Somethin' Extra in the combination? How did it fly?

Flaperons to Elevator mixing.
Dave has the setup described correctly. Having the flaperons coupled to the elevator gives you a little extra lift - your looping maneuvers will be tighter.
You don't need much deflection here. Mine is set up with 3/16" of flap. I tried it with more but the low-speed flight characteristics suffered and it started snapping out of loops.
Make sure you turn them off when landing. The flaps can help you slow down more but if you stall, you'll stall deep. (less airsspeed then normal.) Set up a landing mix with a bit of up spoiler and a little down elevator instead.

I'll agree with most of the above, but may not be totally in agreement when it comes to landing. Also it will very some from plane to plane depending on their individual flight & slow-speed characteristics. Also, it depends on how aggressive your control throws are set.
On my Morris the Knife, I have my 2->6 Mixing set up so that pulling Up Ele (CH2) gives you Dwn Ail (CH1 & 6 for both sides) and pushing down Ele does the opposite. This makes the tail go down and wings go up giving you tighter loops (and again vice versa in the opposite direction for tighter outside loops). I usually have it set to a proportionate mix of 50% which gives you a good bit of "flap" at full-stick elevator but leaves you enough aileron for manuevering.
It actually gives me much cleaner tight loops than switching to high rates on the elevator, which can cause it to snap out. However, some manuevers (like flat spins) can be difficult with this turned on and may work better with no-flaps on but high-rate elevator on instead.
As for landing, I really like landing with low-rate and flaperons on. I can "harrier" in with plenty of wing lift and set that baby down with a 3 or 4 foot rollout. I have had (knock wood) no tip-stalling with this setup, but the Knife is a sweet slow-flying plane when you want it to be.
Now for those really tight tumbling manuevers, throw the flap mix on and the high rate Elev on! With enough power she'll never quit tumbling in place! (provided you don't let it snap-roll out)
This works well for me, but I'm only running 20 to 25 degree throws on Ail & Elev, so if you go 30 to 40 degrees, you might run into problems, I don't know. I leave the Rudder set to Max throw (about 40 degrees) all the time.
