I've used the sea arms with the 110a and the 110, it works fine in water, but you really have to tighten down to get the arms to not flop around on land. Obviously, in water use is the more important. Assuming the ball on the inon is the same size, it will work as well, but I don't think I've ever used an inon strobe on a sea arm setup. My personal preference between the Z240 and 110a is the inon because I like the Z240's manual controls better.
