You can use the clear silicone stuff you find at home Depot and Lowes. That’s what I use. You just use a long run of it so there’s lots of slack. Slack is the key. If you have the hose stretched out as far as it’ll go, you’ll get reduced action no matter how flexible it is. When you have an extra coil of hose lying beside you, you’ll have no problem no matter how stiff it is, to within reason of course.
And it’s cheap, like 3 bucks for 10 feet. Try that first before you put yourself to so much trouble.
