I think that everyone wants to be a classic post-apo sniper with gauss rifle but:
1. Snipers are hard to play in fonline, especially being squishy and hard to lvl up so what, but there I do not know about them so much, still getting a top tier weapon which is sniper rifle or Gauss is not that easy, so don't think of being that much, as for playing solo, you can do that but don't ragequit when gangs will rape your ass while you try to scavenge some junk.
About skins: FT Skins look completly diffirent comparing to the F1/F2 ones, so they don't fit - to make new ones although you would need thousands of hours work and testing, so don't expect too much.
