Curt, I can see the use of FFM in certain limited situations, but I cannot see it in use by the majority of people that may be inclined to buy one and use it at Peacock since they saw it on the dive-rite site. I would also argue that the use of a block only increases the number of failure points in a system. If one needed to switch regs through a FFM then M/F QDs (similar to those used on the RB 80) could be employed w/o reliance on a block to plug them into. I was as alarmed by the advertisement of the FFM as I was by the other items mentioned, hence its inclusion in the post. I will also admit that since I only dive in caves my view of gear and its applications is toward cave diving. I do realize that dive-rite sells gear to many divers who do dive in a variety of environments and hence may have a desire for such items. But dive-rite is historically directed at cave divers and I didn't post my question to rec-scuba.
