Arbusers

Just started with the bonus bagging system. Hopefully will move onto arbs soon.

Any tips for a beginner, lessons youve learned or tips youve discovered that you wish you knew when starting?

For a bookie the easiest way to find out who you really are is how you "use" your freebets, ridiculous odds, strange games and leagues, you will be limited in a glimpse, so be careful and take the money as fast as you can, that being said, if your bankroll is rather small <5K and you have many friends, go for it, with only one valid reason imho, growing your bankroll.
All this is valid for soft books, bonuses with sharp books follow a different strategy for me, but you need a bigger bankroll for them to be able to profit and not lose money, yes there will be a risk of actually losing money.
Most important thing is read the bonus rules, read them twice, and then one more time. :-)
