Just downloaded the sound pack. There is a small problem with the T34/85 sound. When the main gun fires, the first sound is the default sound. That is followed by what sounds like an updated version of a main gun firing. Then it is followed by the new reloading sounds.
Other than that... IT IS AWESOME
it happens with all new GVs. just update this pack with sounds from other people's packs and it will go away. Mix and match to your preference. Personally i took Mitzu's as my main pack and I use Twinboom's as a filler for the rest. But like i said that's my preference. All the soundpacks are great and are used by many many people in the game. AKDogg's got some great sounds too along with Ranger's
If you want to take the extra 20 minutes, download them all and try em all out. Find what you want and fit it together into your personal set.
I also gotta say that the people who put the sounds and skins together deserve a big <S> too...
