Youngster is always surprising nowadays so I wont be really surprised if he ended up winning the game actually however murray probably will not be letting that to happen. The best bet will obviously be going with large number of game and sets as both of this player wont be giving up their chances
Experience is the key of success to win the race so that I won't do agree with you both about Raonic, Murray is one of the best player, I am pretty sure he will use his some magical shots to make Raonic into great shock and will win this final match.
Murray is definitely going strong since the start of the first game on the first set however raonic is definitely not an amateur either. He is lack of experiences if you compare him with murray but he made it this far so he wont be losing easily against murray. Taking murray to win however is not really worth as mosth sportsbook provide pretty low odds for that
