In 2015 we are planning to offer a "pro series" of Chronicals for the more serious of you that are willing to spend a bit more coin to get the higher end fittings and valves. The bottom line for now is that we are trying to configure and price for the meat of the market right now and keep our world (and cost structure) simple versus having to carry additional skus and inventory. The fittings are all standard 1.5” TC, so in reality most of you serious pro-brewer types have drawers full of the stuff laying around anyway! But we hear ya – just give us some time to get our legs underneath us and we’ll start offering some upgrade options on our Chronical line! Thanks and Cheers!
