E-Slayer Opinions Please.

I just got my hands on a Slayer roller with the no engine, servos, fuel tank for $175 and a clear proline slash body to boot. In everyones opinion what would be better handling...get an e-revo trans and make the conversion or do a Tekno conversion. I would rather run e-brakes and ditch the mechanical ones. Looking for opinions and conterpoints. I'm planing to run an MM with a 1512 d2 or maybe go milder. I will run 1/8th scale buggy wheels and tires.
