It depends on the actual wire gauge/circular mils used more so than # of strands. You shouldn't notice a huge difference between the two as long as they're close in circ. mils..
Is there a huge amount of bite at your track? The reason I ask is we don't have to run anything that low at Coopers, even in our EDM's...mostly 10-12 turns...

YES, huge, people run any were from 7-9 in edm and 8-10 in sprint, Arnie ran a 9 but i dont know about the winds that why i was asking. What did everyone run in mod sprint at coopers, like 11-12 or something?

When Tony set the record in sprint mod the last year running my stuff, he ran an 11 turn. We tried a hotter motor in the dash, (since he TQ'd by over a lap, we were experimenting) and the first time he tried to open it up he did a series of donuts down the back straight.
If you have huge traction, use the hottest motor you can hook up without sacraficing lap times. Be sure to remember to look at the entire run, not just the fast laps up front. Sometimes a softer motor is easier/more consistent to drive, even if you can hook up more. Hot motors are harder to get to "turn in " at the end of the straights.
If anyone witnessed Pete D'Agnolo at the '04 Open Wheel at Coopers, he didn't have the fastest car down the straightaways, but had the fastest car/lap times...

I can vouch for Todd, he built me a 10x2 and it isn't too violent off the corners and is just about perfect for our track. I'd recomend about anything he says about motors.

If you have the finesse you can run one pretty hot also. They are great to practice with, they will really teach you how to drive. If you go from a really hot motor back to a slightly slower motor, you will be able to feel whats happening a little better. If that makes sense.

alright thanks for the input, its just that i still need to know what u guys think about single or double winds, it sounds like double is the way to go, but i was jsut curious. My track people run 7-9 in edm and 8-10 in sprint, very high bite and a lil bit bigger than coopers. I ahve a 10x1 cobalt but i want to buy a nine incase i need the horsepower but didnt know if i should try a double wind thanks guys

DC: You really won't feel a huge difference on the track from a double to a single...Not nearly as much as from going to a 10 to a 9.
The double will typically provide more mid-top end, with the single providing a bit more bottom. This is a general statement, as it really comes down to wire size moreso than # of strands.
