I would concider something with a higher amp handling capability- a forwards/brake only boat or plane esc would be cheaper, and some have rather good specs such as 200amps and 6s etc. Then again, if a bk9920 can do 5s with a 7xl, you might be fine.
ok cool. im thinking about just dong 2 6xls, 2 4 cell lipos, 2 mamba max esc
Sweet Jesus.... that thing will be stupid-ugly powerful/fast. BE prepared to be constantly buying replacement parts.
Just imagine a top fuel dragster, and then imagine that... times 10.

I would actually consider putting two 8xl's in that, you will get the same topspeed (can pull higher gearing), and it will tame the beast on the acceleration aspect.... well, somewhat.
