Their drivers take a while to season, but I've beat up some Volts and new Shocks just enough to start seeing more glide and a later fade. Its not a huge change and doesn't really show itself under 375' of D.
Either way Volts and Shocks behave a lot differently at 400-450' than 300'. A lot of people talk about their Volts being TB style flights, and I see that when some of my buddies throw them, but they have turn for me for sure. same deal with the Shock, I've seen some of my buddies make it fly like my XXX, but I can keep one 100% straight for 400' before it thinks about fading with a flat release. It's still extremely reliable at those distances, even into wind. MVP absolutely nailed the OS slots with this driver and the Tensor.
