Thanks John, sounds good. I guess I must have regular size stix floats at the moment.
Just to be clear - you don't need a float belt around the macro port with this setup? If so it seems like less than I have now as the port float belt has 7 or 8 floats on it. (I have the old 105mm and the manual focus port if that makes a difference?).
Yes, I do not use the float belt with macro setup. 6 jumbos and two regular stix floats balance the rig nicely. I'm sure the float belt works well too, I've just never tried it.
Like you, I went from Ike DS-160's to Z-240's. It's surprising how much more negative my rig is now. I used to get away with 2 Jumbo stix on each side with the 8" dome. I do like the Z-240's better; learning curve was a bit higher, but they are much more flexible in use in my opinion.
