thanks for input on guns; need same advice for first pair "real" spearfishing fins; considering a few middle of the road fins: mares razor pro and a pair by mako; the mares are about $150 and the makos are $90. not looking to break the bank but would like a decent functional pair. anyone have any experience with either of these fins? or have a personal favorite? want interchangeable blades for ease of travel; about $150 is as high as i want to go. thanks.
