1/8 scale buggy conversion - help please!

Not to take this thread in a different direction but I'm surprised so many of you seem averse to the 4mm connectors...honestly for the last few years I've been running the 3.5mm connectors on my BL 1/8th truggy. With the ESC I'm using, I *have* to use 3.5's from the ESC and they were on the motor so I never changed anything.

In a perfect world, what connectors would you guys want to use? 4mm? Something bigger?

Thanks,

DM
