I've been looking at the IBtanks...and may try one soon...just can't justify the expense right now. I'm wanting the Lavafire mechanical mod more! And I'm thinking about getting a Bolt for back up, too. Priorities! Haha! I don't have any trouble with the plastic tubes on my current tanks...so I am not in a hurry to invest in the Pyrex or glass just yet. I was curious about the Boge tank 'cause they were on sale for a good price. Have a GREAT day!
