I've been a fan of the Volt since it came out. Luckily I have two of the early runs still, as those are the ones I prefer. As mentioned before, the new Volts will be slightly overstable, but I wouldn't call them "beefy" even in Proton. It takes awhile to wear them in compared to other discs but I have found that MVP drivers wear in quicker than their mids and putters just from the harder impacts that drivers suffer.
I run Motion - QOLF - Volt in my control driver slot, with my early run Volt being the neutral to understable of the trio. Keep in mind the Volt I've had in my bag since they were released so it will take awhile for you to get it there.
The beauty of the Volt (I still say it's MVPs best disc but I'm probably in the minority here) is that is really a do it all disc because it so intuitive. Anhyzers, hyzers, dead straight, hyzer flips, rollers, forehand rollers, forehands....it truly does it all.
I prefer Neutron but again, I'm rocking the early runs so your experience may differ.
