The Aresti III is an ARF.

Of the ones you named I'd choose the Excelleron.

If you want a less expensive choice look at the GSP Swallow. 90 sized & only slightly smaller & heavier than the Excelleron.

IMHO the Zen and G-trick are too expensive.

The brand new Fliton Infinity90 is beautiful and supposed to be available around 12-04 but I read it'll be around $400.00 - and they fussed the Excelleron is too high at $199.-$279. :-))
