After all my research, I finally found that the Virtue Spire had arguably the best combination of reliability, jam proof (So far.. reballs, small balls, brittle balls, etc. fly through), low profile, sturdy build, quiet motor, ease of use and maintenance.
Now, I find that the Spire also has THE BEST speed feed available on the market; exclusive to the Spire. This turned me from my preferential, familiar loaders (Z2 [functionally best], Rotor [aesthetically/structurally best]), which only feature weak, defect ridden rubber speed feeds, save the Exalt.
But I like how my set up looks.
So now, the Virtue CrownSF is available for my favorite Rotor? Oh man.. Since I don't use 'special needs' paint, and don't need to go higher than 15 bps (though Rotor can go as fast, just not as reliably sustained), the only benefit left to grab the Virtue Spire, for me, is the quiet operation.
If I was doing a scenario, where stealth and silence are often imperative, the Spire would blow the Rotor out of the water; but I don't have $200 to blow for the occasional scenario, unfortunately.
So, for now, I'm going to stick with this sexy number, and grab the now available Virtue CrownSF
