Mishimoto Coolant Hoses

Anybody have experience with the lower (specifically) and upper Mishimoto hoses? They claim 5 ply silicon.

This year I've started to see a bit of highway cruise temp creep. Got under the car and my lower hose is getting pretty squishy (no spring). I think the higher rpm's are slightly collapsing the lower hose.

My upper is in okay condition, but is pretty old.

Just looking for reviews basically, or suggestions on other hoses to look at. This is a 1969 Firebird.

Thanks!
