Mr. Mendez,
I've been on record many times saying that I am not as big a fan of win totals bets as many are in the sense that I believe that there is a huge opportunity cost in making a standard 11/10 juice bet that is tied up for 4 months. As a result, I only believe they're worthwhile if they're significantly greater in unit size than a standard game single game play.
What that exponent is, whether 5x or 10x or whatever, is a matter of individual comfort, in my opinion, but the point for me is that if you're going to make them, have the conviction necessary and make it worth the while of those funds being inaccessible.
