6s is less strain.. lower amp draw = happier ESC w/ lower temps. Batteries also last longer (cycles) and typically can run a lighter pack or longer run time depending on the choices you make.

Edit: HW 150a bec is very strong.. never had any issues running multiple good servo's (stay away from savox)

YES, and as noted it's not legal for real ROAR events (yet). I'm sure at some point roar will get their head out of their rear and catch up with every other event rules.. everyone allows 6s at this point for large 1/8 tracks.
BTW with the gear ratio of the tekno etruggy you want lower KV motors, 1350 is your best bet w/ a 6s config. 1900kv-2000kv w/ the 4s config. You cannot gear a 1550kv low enough w/o some mods to allow a smaller pinion. (may not be able to run the center brace at all)
Also worth noting if you stay away from Savox servo's and you won't typically have BEC issue in any setup. Savox are literally the most inefficient servo's you can buy.. why do you think they are so cheap. Will they work.. sure will they ever be in any of my vehicles? Not unless they start paying me to race um LOL.
