Yeh I'm the same/similar really, I only usually bet around £30-£50, if I lose I leave it, if I win I might have a day with slightly more put on/higher stakes. My stakes are usually small unless I really fancy something and the odds are short, I can even play £0.05 or £0.10 on some bets.
And I only try to take them for big bucks with £0.05 - £0.20 acca's. Like today, I will pick 7 horses at Leopardstown and play the 7-fold, but probably also the 6-folds and 5-folds. Then I'll swap a few horses a few times and put several bets like that on, just trying to get lucky at hit 6 or 7 in the day for big bucks. Yesterday I had Final Demand and Lossiemouth in almost every acca I put on, I was slightly worried about Final Demand but not Lossiemouth, I was shocked by that one, but I think you have to pick a couple of bankers and put them in every bet and hope they win. If they do you have a bunch of acca's on the go, if not, they all go down. Today, I'm going to put Romeo Coolio in every acca and hope that he beats Kargese, and probably a bunch of 5 & 6 folds without that race included, as it's probably not worth it anyway.
I do put singles and doubles on and enjoy it, but I'll never win big bucks only picking/placing a few, but still definitely agree that we all often put too many on, especially me, and I should maybe just make my picks and put a little bit more on and not spread it, I just I like to have several chances at big bucks.
