Question Is there a best practice for which hoses should be rubber be flex?

[Ares1590]

Setting up my long hose primary donate routing and I was planning on all rubber hoses except the inflator hose being flex since it won’t really have a chance to get loose and float around anyway and figured it would save weight.

In general though is there a guideline for which hoses should be rubber vs flex?

Personally, I prefer rubber for all my hoses. That being said, use whatever hoses you want. I don't think hose material is ever mentioned in the DIR tapes, but I could be wrong.
