Also Looks like they are having some kits ready for sale by end of February this year, quote from their website:
"High-banker Kits Coming Soon!
We know you all want these! We've been REALLY busy, but hope to have these READY TO SHIP by Feb 2014."
I don't know, but it looks like a shovel full of bank run caused a blow out. Grizz got loaded up big time.
If I had to run a highbanker like that, I'd definately classify to ½" prior to feeding and not feeding a shovel full at a time.
