MA packs are overpriced and overrated. IF they were marketed as budget packs at budget prices, I wouldn't have a problem with them. When the MMM came out, a lot of us conversion guys started having trouble with puffing packs. The MA packs could not deliver what the MMM was asking for. TrueRC or Zippy packs are the way to go on a budget. Personally though, I won't use anything less than the best in my 1/8's. Enerland (PolyQuest, PolyRC) or Thunder Power packs are all I use. For 1/10, the TrakPower packs are noticeably better than anything else I have tried.
