2275 is supposed to be even better about not contaminating fluids than 2075, that was my understanding anyway. I spent 15 minutes reading about both types and decided that an extra 10% cost was worth it if the tubing lasted a little bit longer... 10% extra is cheap if it means I have to change it less often
I agree with you that it's a real btich to work with, I used extra thread tape on all the barbs and cinched the tubing down with hose clamps. The extra work isn't terrible if you're expecting it but it's definitely not as easy as 3603. I wouldn't use zip ties or plastic clamps with this stuff.
