3 words, oceanic mini shadow...
i tried many masks, not the 3 you listed though, i found that for spearfishing, field of vision is probably more important than low volum, the big eyes is one of the very good masks i tried, but now i tend to use, framless one window masks..the mini shadow has a wide field of vision and quite small and low volume....

another good choice would be the Sherwood Mako, still small, but bigger then the shadow:
