I usually pick just one horse in the each of the first 3 legs and play multiples in the last leg so if I win it is just one ticket. Something like 1-2-3-1/2/3/4. I usually bet 3-4 horses in the last leg and hope a longshot rolls in. Costs me $6-8. It can payoff nicely if a heavy favorite doesn't finish in the money in one of the first three legs.
