Info about the BK 9920 on 6s

[lincpimp]

I know that there are better escs than the 9920, but I have one and would like to get some feedback from the guys running them. I have a new emaxx center chassis with tranny coming (thanks Sike!) and will be trying out my KB45 8xl on it. Do you think that the 9920 can handle that motor (1700kv) on 6s lipo? Motor speed is less than 40k rpm, but I intend on gearing for about 70 with the 2 speed. I can imagine that this will draw alot of current. What kind of ratings can the 9920 handle? It says 99 amps, but can it do that?
