Whatever you decide to do I would recommend staying away from bonus buys if you plan on playing £50 a week then you’ll blow through that in about 5 minutes with bonus buys and most of the time you end up with a massive loss from these and with not really having had a proper session you’ll only tempt yourself more to deposit again or find somewhere else if you have limits in place.
Better to do smaller spins and get a few bonuses that way even if they are rubbish you’ll find it easier walking away after a session or at least I do if I put £50 in and have a few bonuses it’s so much easier for me to walk than if I lost 5 bonus buys in a row.
Maybe it’s just me but whatever you do make sure you put limits on your accounts.
