Help with motor choice

[generalg]

Since ordering the FLM savage BL conversion I've been trying to figure out what motor to buy.
I had already bought one of the 1800 Great Plains Ammo motors from Tower for $35 and now after more reading find out it might not be enough power to push the heavier savage around...


Here's what I know for sure.

Planning to use the Mamba Max with UBEC from Castle.

Want the longest run times possible with the most torque for wheelie's on command.

Also I have the FMA CellPro charger which will only accept or charge up to a 4S pack.

ANd most importanly I don't want to take out a loan for a motor.

Have been looking at the 8XL through 10XL Fieago motors here:

Or is there other motors I should be looking at?

Thanks
