He goes bigger on the Arb's because they're risk free and require a large amount to make the payout worthwhile. But a 10 unit play = big risk. It doesn't matter how much actual money his unit is. If he's a $10/unit guy, then $100 is a big play for him. Whereas a $200/unit guy would consider $2,000 a big play. Either way, each guy's risk is proportionate to their bankroll and what they are used to wagering.
As far as money management, it is common to use somewhere from 2-5% of your bankroll as one unit, and then rank your plays from 1-10 units (10 being the biggest play you'll make). Doing this, your max bet would never exceed 50% of your bankroll and that would only be in rare cases. For the most part, a standard 2-3 unit play would comprise of 10 to 15% of your bankroll. As you increase your bankroll (hopefully), your unit increases, but the rules stay the same. This is a good way to keep you from getting overconfident and taking big losses too quickly by increasing your wagers disproportionately to your bankroll.
