Cromor is not Cyclex, it's Cr-Mo. Not sure if it's seamed or seamless. Cyclex is used on SL/SLX and the ilk. Cromor falls at the bottom of Columbus's range of butted tubesets. It's thick and heavy, using standard tube diameters. There is nothing wrong with thick and heavy as long as you know that going in. Personally though, I'd go OS unless you have a reason not too.
