What to do...

Ok, I'm sort of in a pickle here...

I have my BL LSP with a 9xl and 5s(one 2s and one 3s) 4000 maxamps lipos. I am very happy with the power. I also have a BL rc10gt and I share lipos between the two cars now, and it gets kind of annoying. Also to charge the batts with my Duretrax Ice I have to charge one at a time, and that takes a long time. I think I would like to buy more lipos for my LSP, either 8k or 10k. So here's what I came up with:

Situation 1:
Get new charger (mrc 989) $140
10k single 5s pack (maxamps) $260
Keep 9xl

Total: $400:019:

Situation 2:
Keep my Duratrax Ice
8k single 4s pack $220
Get new motor 7xl or 8xl to run 4s on $90 (don't think 9xl would be too powerful on only 4s, what do you think?)

Total: $310

Also how would run times be with the 7 or 8xl with 8k lipos? I get about 30-35 min. with my 9xl 5s 4k setup...

Thanks!
