eh, i was disappointed in it. it is still in beta so it can be easily changed... but it seems like most of the community gave up on it and don't really care anymore. It seemed way easier than 1.6 seemed like barely any recoil and you could just tap constantly... you wouldn't have to stop tapping when shooting to control recoil
Pro mod was always going to fail for one simple reason. Source players like source and 1.6 players like 1.6. Why would any of them leave to play some bastardised version of source.
