Yep it's not worth risking as you now know.Knowing the HR spool has a design flaw I thought I'd risk it. Sure enough the rubber o-ring allowed the pin out and resulted in a RWD Kraton.
Result was 76 mph, when on the brakes the rear fish tailed and sent the rig over the curb where it began to cartwheel.
So glad your Kraton survived the crash better than my Typhon did though when it went the same way.
