Thoughts on this set up

[Scott711]

So this is my maiden voyage on this forum and I'm looking forward to hearing your comments.
Currently I'm sportin a fully loaded Supermaxx truck with racer x suspension and a torpedo chassis. I've been running a HV-maxx on 14 cells but not satisfied with the performance, so now I'm looking to move up to a more powerfull BL setup.
The truck is weighing in around 12+ pounds all loaded up and I want to be able to use 16 cells if I choose.
Here's the set up I'm considering:

BK Wanderer 8XL
BK 12020 controller
Motor clamp/heat sink
UBEC
Strobe slipper kit
51 tooth nylon ofna spur (mod 1)
12, 14, 16 tooth pinion (mod 1)

I should tell you that I enjoy bashing around the negiborhood and bmx park when I can get there. I'm currious to know what listed here is over kill and what is nessecary and what speeds and run times I can get from the various setups.
Thanks in advance for your help.
