Need some help to choose LiPo

[mothman]

Hey guys,
Im still new here. Thanks to Serum, the BL savage Guru. He's the one who encouraged me to join this great forum. Its a very good source for those who wants to run BL.

Since Im planning to convert my savage to BL, I need some help from you guys. After all the reseach, Ive decided to use Feigao 7XL and Warrior 9920 combo. I'll get these from Mike as soon as they are available. I'm also goin to beef up my drivetrain. Here are wat Ive planned so far:

1. MIP CVDs (Ive already have this on my truck)
2. 4 diff gear mod with Lightning cups or Nova Alum cups (Just need to get the cups as I already upgraded the diff gears)
3. Hot Bodies Mega Travel Drive Shaft Center
4. GPM gear box
5. NEW ERA Bulkheads (already on my truck)
6. HD 2speed upgrade
7. Monster Paradise conversion kit

Thats all I can think of right now. Please feel free to give comments and advice about my plan to bulletproof my drivetrain

Ok my question is, since i would like to get a decent runtime (20-25mins), Ive decided to get LiPo. Ive heard about Polyquest and Kokam, but not sure which one shoud I buy. Im not really looking for speed. 35-40mph is more than enough for me as Im not a good driver:o . Tower is having sale till this wednesday so I think this is the right time for me to get a good LiPo packs . These are the packs that Im interested in but not sure if they are good enough for my BL savage project:-

Or should I spend abit more and get the PolyQuest like either one of these:-

Or is there any better place that I can get these kind of LiPos?

Sorry for this long question. But I really need you help. Please shed some light. All help, comments and advice are greatly appreciated.
