HELP! Need a quick answer!...

Ok guys, I have saved up enough money to purchase a higher end BL motor for my LSP. I have narrowed it down to a couple motors:

Neu 1515 1y/F

Neu 1512 2.5d/F

LMT (Lehner) 1940, What wind? 7 or 8? (cant afford a 1950:031: )

Pros and cons of each?

I will run a maxamps 8000mah 4s lipo on a quark 125b so 4 pole motors are not a problem. Anyone know the approximate run time of this setup?(geared for 40mph)

Thanks in advance!

*edit* I forgot to mention, I want to buy it tonight!
