ScubaPro MK25/S600 Hose Specifications?

[MaverickNH]

As I have a ScubaPro Air2 on a ScubaPro KnightHawk BC, I'm looking to replace my 30" OEM S600 regulator hose with a 40" yellow hose, so my buddies, who have standard yellow octos, know to just go for the yellow. I'm looking at Miflex hoses, but am not sure of a few specifications:

1. Diameter - Do I want 3/8"?
2. Pressure - I thought I was looking for HP hoses, but Miflex lists LP regulator hoses. Is this what I need? http://www.miflexhoseshop.co.uk/acatalog/Regulator_Mellow_Yellow.html
3. Connectors -Do I want Miflex standard 3/8" M UNF x 9/16" F

Thanks - I searched about, but just got more confused...

3/8' LP hose with standard female end.

(HP is for the pressure gauge)
