I don't know if this was ever proven, but I heard when I bought an auto CG13 that the auto blocks were stronger as they had extra fins on them or something.
Anyone know any more about this, I'm going back to 2005 here! :laugh:
Yep - 1.3 only as they have a bit of support at the top of the deck - not fully closed deck, but should be stronger. I might have a pic at home if there is much interest?
