I have a 6 foot SMB and a Halcyon Defender Pro spool, so I have not used the SMB pocket.I have the Paragon too. I stuffed a 3 ft SMB into the BP pad pocket with the D-ring hanging out the bottom and attached to the rear D-ring with a double ender. Out of water I pulled it out to see how it would work. Seemed okay, but not sure how it would compare to other methods because I have no experience other than the little I did at certification.

Halcyon Dive Systems
Halcyon began as a group of divers who knew exactly what they wanted, but could not find it in any dive store. Our passion for diving led us to designing wings and lights to satisfy ourselves.
