Re: Will the KM be an upgrade?
Easier draw probably will be the main thing, especially if right now you are using mya hoses.
KM hose will give a better draw than a mya hose on any rig....and due to the mya having autoseal(unless you took it out) and mya ports being slightly smaller in general the draw is a bit mroe restrictive than KM. An easier draw allows for easier generation of large clouds.
EDIT: i missed the part about nammor hoses....but yeah...KM will still probably provide a slightly easier draw.
