I drilled the center "corss hairs" out of my CPCs and never had them clog. They are "nice enough", but go stainless if you can. The CPC ones, while they handle heat well, never felt sanitary. Especially after I drilled them out.
The thing about the Tri Clamps, they are pricey but they will last almost forever if you take care of 'em. And they are truly sanitary.
I bought these (through my LHBS through Fox Equipment) and found out right away the cross-hairs had to be removed to prevent clogging. I've had them on my rig for about 4 brews so far and find them pretty easy to use and not hot to the touch.
If you plan it right you can make a couple of hoses that do more than one application. I use a hose from the hot liquor tank to the mash kettle and then use it from the ice bath (formerly hot liquor tank) to the wort chiller with another hose returning to the ice bath.
The only QD that seems difficult to snap on and off is the one on the outlet of the boil kettle. Heat may be a factor there.
