Just my limited experience.
Just built my first MLT, and went with the SS braid.
I put a heat resistant tube with slits cut on the bottom inside of the braid to keep it from getting smashed, and ran that tube up to my connection. So far so good, on testing I get around 1/2 cup of water left over and I can't see any water when I remove my grains after I'm done.
I may also make a manifold out of CVCP to see if I get any better performance, just to see if works better for me, or just if it looks cooler. I'm convinced the gadgets and toys are just as enjoyable as the final product.
