I would go for the HV system simply because its sensored, you will have a smoother pullaway which is really important in your situation. Ideally run it on 14 cells, with a fan on the controller to keep things cool. Just gear really low otherwise your asking for trouble :) Normally I wouldn't recommend the HV but in your position it is really important to get the extra smooth pullaway the system provides.
