LIPO Suggestions for an SC10

[nutey]

Looking for some suggestions on what LIPO to get for an SC10 running a 10.5 brushless and LRP Sphere.

Currently it's got a butchered Trakpower Saddle Lipo which is ok for messing around but not really ideal for racing so I want to invest in a decent (ideally legal) Lipo.

I've been looking today and was wondering whether the extra cash for one of the LRP/Nosram 5900 Lipos is worth it over say the Vampire Lipos..The Intellect ones appeal but if you end up getting stung for Duty from HK then the cost saving is completely gone. I can only really afford 1 so was thinking of getting a decent C rated 5000+ one really...

Anyone got any suggestions?
