Been trollin the boards trying to make up my mind, was going to get the TC-4 but its been out of stock every time I've tried to buy it. So its either the maze or spiral I guess, but I can't seem to find a definitive answer on which is better. I have a Eheim 1048 with 3/8" ID tubing & a black ice prime, cooling a XP 1600+ oc'd to 1750 mHz. It's got an old maze I on it right now, think it's finally time to upgrade

Any help would be appreciated...
