I like the 7750's wobble... when it (rarely) happens, if feels like it's "talking" to me.
But, if you don't like it, don't go back to the 24...or the 243 for that matter (another great choice).
In the 47mm size, I'd go for the 1305, as I think the new thinner case and blue had work well for that submersible.
The 692 is an awesome choice, but I don't know if it's available yet? The BMG tech and blue dial seem really cool.
As for the 682, the design of the sub lends itself well to a smaller size, IMHO. It's probably what I'd go for, but I'd need a side by side with the 1305.
Good luck with the hunt!
