I have put two hoses together with an Osprey quick connect. The hose easily reaches my mouth, and I have no problem drawing water. I put the hose joint inside my frame bag so that there is no need to disturb how the hose is threaded into the bag when you pull the bladder out to refill. Works like a charm.
What kind of reservoir are you using? Or does it really matter with that kit? That's a great suggestion, btw!
