I have the HHA but mine is the 3 pin ,best of both worlds. Never any problems with HHA ,I've had a couple . If I did have to.make a complaint I would say the pins are too bright ,I went with .01 to keep the light burst down as much as possible.
I got one of those goose feather jackets this year that packs up really small ,it has been a game changer the few times I've pulled it out and wore it ,I couldnt imagine walking around with it on though.
