If you want to mix cappers, the good way to do it IMO is getting on the particular capper after 1-2 losing nights - just the law of averages. I always look through the comp plays of various touts (but those more serious ones) - if there's one on a losing streak, the game they advice becomes more attractive.
I don't know how much you have in your bankroll and if you can afford to lose this money. If you deal with 10 or 20 K, be most cautious. If you have 500, you can place a 10% of bankroll wager without any sweat I think - but in this case your chances to get to 50K this season are quite small. It is posisible to raise your bankroll significantly (it was my case for instance), but there's a lot of risk involved - propose to use excel and do some experiments basing on your or someone's stats. Generally, my personal opinion is to limit the number of bets but increase the size - of course if you can afford to go broke, as betting over 5% is very risky and the ups and downs can make you really sick (however IMO without aggressive money management it is not possible to achieve spectacular succes - on the other hand, the more I have in the bankroll, the more conservative and cautious I get). Read something about Kelly criterium
BTW, there's a Danish betting site where they propose bets on usually very chalky and little known games, advicing bets equal to 20% of your bankroll. This season their bankroll is up from 10K to 35K, and that is not their first season.
Maybe you should try if-bets? I like it if I have one game of the day that looks far better than others - the risk-reward ratio is good in this case, but it can really piss you of if you have an if-bet of 3-4 games and only the 1st one fails:sad3:
And don't forget bonus hunting, 20% on you bankroll at one shot it is something that cannot be missed
