XB4 6-hole pistons

Has anyone used the XB4 6-hole pistons yet?

Most people seem to have built it as kit and used the 3-hole pistons. Just wondered if anyone had tried the selection of included 6-hole pistons.

I built as per kit, which was fine on the carpet, but loose on the gym floor. The car was great over the jumps, but rubbish on the crash mats. I think I was over damped, after talking to others running 4wd (410/b44/etc), so am looking to lighten it up. Other XB4's looked the same as mine on the crash mats, but they had setup similar oils/pistons.
So would going to thinner oils with the stock 3-hole pistons be the way to go, or stick with the oil and use one of the three sets of 6-holes?

I ran mine std and yes I think for carpet it's pretty good but bumpy astro there's far too much pack ! I rebuilt mine with 6 hole 1.1 front 1.2 rear 350/450 core and it feels a lot better . Glenn

As jay mentioned I'm messing about with the 6 hole pistons, 1.2mm front and rear, 450 cst front and 250 cst rear right now (50 cst lower than my durango).

The rear may just be a little under damped, I do want to try the softer rear spring though...Can't really report on how they where working as my car was rubbish, due to the rear diff loosing its oil!
