...ok cheers for that, appreciated.
I guess the only way to find out is to try it out for real! I've set myself up a starter amount of £80. I am planning on working through the 'Easy' offers with OM (most are bet £5, £10 or £30 and get a free equivalent bet type offers), one at a time. i.e Sign up to the first offer, bet the qualifier bet (and lay it), wait for the free bet to be added to my account and then bet the free bet (and lay it) and then bet a mug bet (and Lay it) and then withdraw winnings from both the exchange and the bookie and then sign up to the second offer and repeat the process.
Is this a good strategy for a beginner like me, in order to learn the ropes?!
