I'm slowly making the switch from Masterkleer and Tygon (3603 and B-44-4X) to PrimoChill LRT. I use the 1/2" ID x 3/4" OD, but the bend radius kicks the crap out of Tygon and Masterkleer that I've used. Its very good tubing.
I thought the duraleen(sp?) rating was higher on the masterkleet, that tygon is poo though. .
i'd get masterkleer white or black as its like under half the price of the primochill tubing (biased... I just brought some like 2 hours ago after reading a review) lol
