Is Maxamps any better now?

Hey I've been reading post over many rc site trying to find the good setup for me. I need to be pretty sure of what I'm buying before doing so because I can't afford to make a mistake and waste 200$+ on battery or any other part I update on my e-revo. Brushless update cost so much!

I finally decided to order the tekno neu 1515 1y squared I'm gonna use with the MMM I got some months ago (wish it will hold down it's V1) and never used.

Now I'm looking for the right lipo to go with my kit. I've seen many and am pretty lost with all the post read. Here's the pack I am wondering about:

MA (yeah I know) 3s 5250Mah 30c x2 for 22.2v - about 350 they told me I could get 15% discount

Neu energy 3s 4900mah 25c x2 for 22.2v about the same price

A123 cell 4s 2300mah x2 in 4s2p setup with a 3rd pack of 3s2p for a total of 7s2p 23.1v 4600mah 30c. About 400$

I've been using home made a123 5s1p in my e-revo for some time and they miss a little punch, but that might be my soldering being pretty bad! ;) I heard well made pack have a lot of power.

Any of you have comments on my ideas, or other pack to recommend. Is the MA good even if they don't stand their claimed C rating or should I go with something else ? I don't want to hijack the trade but u seems to know what u're talking about in here!

Thanks for your help!
