Miflex are Nylon, EDGEFLEX is Poly. generally speaking nylon is softer and more flexable, Poly is more abrasion Resistant> Miflex has the patent on using Nylon, I wouldn't anyhow.
Thanks, Jim. I looked at the EXP and it does seem like a great value. 2 HP ports is not necessarily a solid requirement if the rig is good otherwise and priced right.
The Edge stuff comes with nylon hoses too, which seems nice... I'm familiar with Miflex hoses, do you know how the Edge nylon hoses compare? (However, I'd need a 5' hose on the primary, so I may still have to eat the price of the included hose.)
