I'm campaigning for converting the Cobra trailers to electric brakes.

+1 -and let me help you get it started...

Dear Mr Spindelberger, surge brakes suck. I'd rather have no brakes
than deal with the large range of well known and predictable nonsense
that accompanies that outdated overpriced unreliable system. Cobra
should at least offer electrics as a stock option, or at least without
any brakes so we can convert them ourselves with the extra 2 grand
that wasn't wasted on junk running gear. These aren't your father's
electric brakes...

-Paul (guy who's towed a lot of trailers a lot of miles and also knows
of accidents directly caused by Cobra brakes)

ps. I have a 10 point list I've thrown out a few times around here in
the past, of why electrics are clearly a better option for glider
trailers in case anyone still clings to the notion that their surgies
are better simply because that's what they have. I mean, the most
expensive glider trailer would obviously come with the best system,
right?
