I have updated my Mestis pack, so here's the
2016-17 Mestis pack for FHM3.
It contains the league logo, team logos, player and goalie helmets for each team, and, of course, updated jerseys. Some jerseys are not 100% accurate, but at least they are realistic.
Extract to your saved game graphics folder or to the quickstart_games\OpeningDay.quick\graphics to have them when you start a new game.
