Not true!I visit this part of the forum very rarely as I notice this constant BP/W-pushing annoys me. I am fully convinced that the pushers never drink, smoke, eat sparingly and healthily, avoid stress, exercise daily and have a perfect BMI. I'll quit my rant now and wish you best of luck.
I'm not sure. If i look at google, i see several sources mentioning back inflate (it is not). It may be the so-called bladder retraction system i described earlier. That might make it hybrid-like although frankly i have no clue what hybrid should entail in this context. When inflating, i mostly notice air on my back. Only when fully inflating (rarely) I feel the sides really inflating. This may be the reason.I just looked over the Aqualung BCD line and it appears the OP made up his own definition of hybrid as being between a back-inflate like the Rogue and a full jacket with cummerbund like the Pro HD.
