What do you guys think about these? Good way to make a lot while risking a little or sucker bets? I am torn.

Ever been to Vegas? Those ritzy high rises are built by all that play parlays and teasers. A great capper hits 55-60%. A Hall of Fame baseball player hits .300. A journeyman hits .250. What is the difference? 1 hit every 20 times at bat! A Hall of Fame Capper hits 55-60%. A big loser hits 50%. What is the difference? 55%= winning one more game per 20!! Same thing! That means no matter how good you are, how detailed your capping is, only going to get you 1 more win every 20 games capped, at 60% it is 2!!! So if you make just 1 parlay, or teaser wager and lose, guess what? You have now reduced yourself to the same level as that 50% capper, and you go from Hall of Fame, to loser!!!!

Agree 100%. Sucker bets. Not only are they very hard to hit (often do you go perfect?) but when you do hit, they don't pay the odds they should. While they are exciting to play, you will lose money over the long haul with them. When the sportsbooks want you to play something, don't just walk - run away!
