    I have a set of mavic cosmic carbone sl wheels that I am thinking of upgrading. What would be the next step up for an decent upgrade? Wheels that would make a noticeable difference.

    It is very difficult to say. Wind tunnel tests should be done with a rider on board, but they usually are not.

    http://www.slowtwitch.com/Tech/Mavic_Wind_Tunnel_Challenge_2991.html

    "Test subject A was what we’ll call a “semi-aero” titanium frame with slightly ovalized tubing, but nothing extreme. Test subject B was a then-cutting edge carbon aero frame. Sans rider, the frames showed a fairly significant difference in drag (the carbon frame would cut about 50-60 seconds per 40k at 25mph). However, when a pedaling rider (Kevin) was placed on each bike, there was no measurable difference in the two frames. Zero, zilch, nada."

    Or you could just buy some Zipps and convince yourself those thousands of euros have made you faster.

    Zipps? Pfft.

    Get something really deep and outrageously expensive. You'll absolutely, 100% convince yourself they're more aero then.

    I like Enve wheels.

    You could really break the bank on lightweights though.

    To be honest I think most A4/3 riders would be very happy with those wheels.

    No, the wheels you have are grand, any performance boost will be close to immaterial. If you want to get out of A4 upgrade the engine!

    or consider a powermeter if you don't already have one.

    It's finely tuned the engine. The pistons are in full motion. The cosmics will be on fire so will need replacing :-D
