I received the Indigo this week and I tried it in the water last night.
It is my first BP/W, and I had no previous experience with a back inflated BCD. I have used for a few years a bulky Mares Morphos BCD with the air trim device.
I already love my Frog wing, it is way more comfortable than my old BCD. The hog. harness was fun to set-up (never done that before) and it is easy to don and doff. In the water it keeps the wing much more firmly attached than my Mares' harness.
The build quality of the Frog looks very good. I was able to compare it side by side with a Halcyon Eclipse that a friend of mine was using, and neither of us was able to tell the differences in terms of design and materials used. Time will tell if it is as solid as the H.
Weight-wise it is the same as my other Mares, give or take a couple hundred grams, so travelling with a S/S plate plus the STA does not appear to be a big issue. On the other hand I was able to remove 3 kilos from my belt, leaving only 1 kg on it, which I will try to get rid of at the next dive (I am using a semi-dry 6.5 mm suit).
The only thing I was missing last night was the airtrim, but I think I will get used again to a standard inflator in no time. Another plus for the Mares was the higher comfort when floating on the surface, but this is no major problem and I guess it is a common issue with all BP/Ws.
So far I am totally satisfied with the purchase. Considering that in this part of the world (Europe) the Frog Indigo costs over 35% less than the Halcyon Eclipse, I would say it is not worth shelling out the extra cash for the more popular blue-H option (take my advice for what is worth, I do not have an extensive experience).
Ciao,
