which servo, hv or standard

[Dazzle]

Looking for a decent steering servo for my TM2, but not too sure on whether high voltage would be a better choice over standard. Any input, or thoughts welcomed please.
Thanks Darren

I run hv in my 1/8 cars an wouldn't swap back but for my rb6 I use a 7940 on 6v which is good but the xpert 3401 I have is favorite been very impressed with it though the hi-tec's a better fit
