futures wagers are sucker bets simply because books actually charge a ton of juice on them. I personally would suggest picking 2 teams and going with it. For example in the NFL I really liked the Niners and took them midway through the season to win the NFC at +1200 or so when they were still in playoff contention. In the NBA I like the Clippers and took them when Paul was out when the public perception on them was low. Always try to get the best number because it really makes a difference. Have a strategy going into the season and have a team you like and wait till you get the best number on them. As far as your picks no clue who wins the NHL, but I have a futures wager on Chelsea I locked in during the group stages. The other teams are simply not worth betting at those numbers. +190 is simply not worth locking your money up for two and a half months
You are looking for "Pro" help... so I'm a just an average Joe and just curious how you came up with the averages +150 and +148. It looks like you know what you're doing here and smart enough to need any help. Just one comment, it's too early for any hedges.
