Best vario combo for a GTS 300

In a while i have to replace the vario weights and 'm thinking about changing the vario for a Malossi or some other make.

Unfortunately i don't now what make or set up to choose for.

I've been looking for dyno tests but have not found one.

Any ideas ?

I'm thinking about a set up that gives best acelleration between +- 50km/h and 90 km/h.

(entschuldigen für die englische Sprache, Ich spreche kein Deutsch)

I remember a test of vario's on a GTS 250...

I think it was in Scootering magazine...

Anyone has this test in pdf or something...
