Acrobat Recommendations

Alright, I'm at another impasse, this time about my acrobats. I've come into a few more lately, and I'm not sure who to really focus on for that push to 5SB first.

Essentially, the two that have come up on the forefront for me are Andrade (4SB, no gear) and R-Truth (4SG), both unleveled. They seem like a bit of a step up from my Rey Mysterio (4SS, 1 gear, leveled), but I'm contemplating if it's worth waiting however long it takes to scrape together 20 million or more coins to get one of the other two up and going, or to just level Rey up to 4SG and eventually 5SB and focus on them later.

I also have other acros who might work but I don't have nearly as much of an interest in bringing to 5-star eventually - X-Pac at 4SG, Jimmy at 3SG, Macho at 3SS, Sting at 2SG - but I feel that if I do get an answer, it'll be either Rey, Truth, or Andrade.

Any advice would be very much appreciated!
