Neu motors... can't decide which

[jnev]

I know I'll be upgrading to a Neu motor soon, probably the Tekno version, and I am having a hard time deciding which one to buy. If I get the 1515/1y, I'll keep my current battery and buy another. If I get the 1515/2.5d, I'll keep my battery and buy a 6s pack and I can run both, or I can buy a 1515/3d, sell my 4s pack and buy 1 6s pack. I think the 3d on 6s will be the most efficient, and running with a 20t pinion, I will be at about 42mph which is perfect for bashing.

But the nice thing about the 1y, is that I'll have two batteries to run... and with the 2.5d, I can run any voltage from 4s to 6s with decent speed and power.

So what do you guys think I should do? I have a MMM coming from Mike, so I don't need to worry about an ESC, just can't decide what motor out of the three.

Thanks in advance guys!
