PM-Performance:Any opinions would be greatly appreciated.
I prefer a fullsuit and hooded vest for a layered suit.
A Farmer John/Jane can provide the came rubber coverage but since there is no single membrane it's bound to have more seepage than a full suit. Some like to use the pieces separately but while they might work for that that are not IMO the best choice for the primary use. Depending on the strap arrangement of the John you can end up with as much as 3 layers of neoprene on your shoulders once you add a hood.
I am also partial to hooded vests. The vest will mute any seepage from your back zip and provide great closure of your neck openeing. All this in addition to providing 2X coverage on your all important core.
The hooded Bare suit you mention sounds like an Alpine. When you add the hood to the suit the fit becomes that much more critical, if it fits you just right it could work. You will be pretty much commmited to that weight of hood all of the time.
I dive mainly my Bare Arctic in wetsuit season
In the warmest months I wear a 3/5 hooded chicken vest under the Arctic.
In the cooler times I go with the 7mm hooded step-in shorty worn over the Arctic. The cheek zip is not noticable at all during the dive. As you step out of the water you can pull it down and open up your entire neckline, nice.
If it's real nice I can wear either of those vests with my Bare 5/4 Velocity.
I have even worn the 3/5 hooded chicken vest under my 3/2mm fullsuit.
