Aquanaught,
First let me say that I am not affiliated in any way with Mares. Got my handle from my dive buddies for buying so much Mares equipment.
I tried the Dragonfly(DF) earlier this year and wound up buying the Morphos Airtrim. There was nothing wrong with the DF, it was just a little too heavy for me, which is why I went with the Morphos.
The DF is a well built BC and very rugged. Has more than enough D rings. It won a testers choice award from Rodales and DiveOZ Australia. I love the Airtrim system as I can trim in any position and the control is always in the same place.
It really depends on the type of diving you will be doing. If you plan on using doubles or tec diving, you may be better off with a BP/W. The DF has a kit to support doubles, but it also adds to the weight.
Whatever you decide, best of luck with your choices.
Dive Smart; Dive Safe
Enjoy the ride
