I have a Zeagle FH6 that I looking to switch to Miflex hoses. Looking for input from current users of these hoses about lengths to go with, I'm looking to bungee the octo. Thanks in advance.
Are you planning on converting to a "Hogarthian"-type hose setup, using Miflex hoses? In other words, 5' or 7' primary hose to donate in an OOA situation, and 22" backup hose? Or a variation of that?
Hose length is really a personal preference type of thing (unless diving a strict Hogarthian or DIR configuration).
With my single tank BP/W rig I'm currently using a 5' Miflex hose for the primary, and a 28" "normal" hose for the bungied backup. I could have gone a bit shorter with the secondary hose, but had thought that 22" might be too short for me. I'm happy with this setup for the type of diving I do. I'm a tall guy (6'5"), and normally a 5' with traditional long hose routing would be too short, but with the Miflex it works fine because the Miflex will tolerate tighter bends without trying to pull the reg out of your mouth.
Some use 40" as the primary with a bungied backup. A 40" gets routed under the right arm, and you generally add a 90 degree elbow fitting to the 2nd stage to aid in routing. The 5' or 7' hoses also route under the right arm, across the chest and behind the neck; the 7' will have extra length that either needs to be tucked into a waist strap or routed beneath a cannister light, pocket or knife on the right hip to hold it in place close to the body.
I guess the first decision is whether you are switching to a "long hose" configuration, then the other choices will fall into place.
Best wishes.
