Well the Rizoma set includes a top triple and preload adjusters - though on your bike there's no way to actually use the adjusters. But the price isn't bad for Clips and a triple.
There's some good info left on TOB
http://www.ducatimonster.org/forums/accessories-mods/175010-common-questions-regarding-clip-ons.htmlOn set that isn't covered there is Apex.
And of course 50mm clips from any other bike would fit as well.
Giles ones are the most adjustable ones that one can currently get (it seems) but you pay for that. If you can find cycle-cat, they are adjustable without rotating the bars, giles too
Sato and Apex allow you to adjust the down angle of the bars - but it means rotating the bar, which means losening all your controls, and possibly redrilling for your throttles 'nubbin'
i had some of the older (3 bolt) Vortex clips on my 620 and they were solid. The newer pattern from Vortex looks a bit nicer than what I had. There's a few other similarly utilitarian clips out there.
