Sorry mate, I guess when I said it was dangerous, in hindsight all betting is. You can go broke just as quick backing even money Fav's as laying 15/1 shots. It's all about Lady Luck. For instance backing $2 horses for a win says you have a 50% chance of winning, but the maths says you could have a losing run of up to 10 before that next win. Laying a 15/1 shot the percentages say you have 94% chance of winning, but there's no guarantee that your next loss might occur in 10 bets time followed by another 5 bets later. So its all about having a staking plan to recover losses and save you long term. Keep doing what you're doing if it works for you. I just hate laying anything over $6.50, it's just what you feel comfortable with.
