Need info setup for Brushless Savage X SS

Greetings fellow Savage fans. I am jrc, from www.bannedrc.com.
I, too, am new to this particular forum as well as the whole brushless Lipo craze. But not new to Savagery. I have two and a half nitro Savages plus a nearly completed FLM/Addicted2RC black ano tranny forward BL Savage.

I am also suffering from not having a clue as to which motor/esc/battery set up to use. All the different types of motors and all the different specs on the motors and esc give me a headache. I have looked at so many they all are looking about the same.
I trust that most every suggestion here "will work" for a motor/esc set up. I am also quite sure that y'all are convinced that you have the "best" set up. I am not here to argue any of it. Rather discuss it in order for me to get the "right one" for me.
I want my BL Savage to obviously be wicked as hell but I also want it to be useable and not just a silly novelty. I souped up my AErc18b to the hilt and regret it a little bit. Even with the lesser powered 6800kv Mamba competition set up it simply will not get traction - anywhere - any type of tire thus far.
I do not want this with my Savage. Rolling wheelies at 30 MPH sounds real cool to me for sure as does the 50+ top speed.
I guess what I want to know is why do y'all say to get "X" type motor rather than "Y" type motor and ESc and so on.
As I recall the prototype for the BL Savage used a Feigao Motor. 9XL I think it was. Yet y'all have not suggested that motor in this thread. Why?
Again, I am simply being the Devil's Advocate here trying to decide the smart way to go. Like the other fella who started this thread, I haven't the money to experiment and play around with different set-ups.

but I will take a moment to give props to FLM and Addicted2RC for all their help in getting me into this BL Savage kit. They have been fantastic in their customer service skills. I got to go see where they make these kits and was duly impressed. Quite the setup Jamie has over there.

I would appreciate knowing which gear ratio y'all are using also. I was going to purchase a whole "set" of pinion gears but the more I read about the subject, I am starting to think it doesn't really matter that much due to the power of the brushless. I also think my three speed will be better suited for one of my nitro rigs rather than this BL kit the way it is looking.
http://s256.photobucket.com/albums/h.../Tango%20Done/ Here are a few pics of the Lid I painted for the BL Savvy. This is a JConcepts Tango lid made specifically for a Revo 3.3. A little modification to the rear body mount was all that was needed to mount it to the Savage. Perhaps a little bit finky looking due to the longer wheelbase but it;ll do to take out and beat the hell out of. I was not very well pleased with my paint work on this shell this time but practice makes.....well, more practice.
S'all I got for now fellas. Try to not laugh too hard at my paint work. This was only the 4th or 5th one I have done with an airbrush.
