I've been running a mildly acidic juice in an older Vision for several days without any signs of damage to the tube. The extra thickness definitely helps.
The VISIONS are definitely a thicker mil (handling it I'd venture its about a 50% increase in mil but that is by no means scientific) than we have been accustomed to with the other clearos on the market but we like to give that caveat in case some use an acidic juice and it does cause any cracking in the plasti case...
