I used to get annoyed by the same thing, I'm sure some suppliers never actually use the product they supply. Re-inforced pole hose sounds great until you try to use it, it's a lot heavier and and it kinks shut and it wears just as quick!
We don't use rubber hose we use clear PVC hose we find that this stays flexible in use and doesn't 'kink' shut half as easily.
