I'm not betting much on sports, when I play sports betting, I dont really care about the odds difference because my bet is always small amount only which wont give significant difference when it comes to winning bet. But if I have the chance to bet $1000 or more, for sure I'll try to find the highest odds because the profit difference can be a nice amount. Of course it will also depending on other situation, I mean if I have my money on one specific site already then I think I wont switch to other site just for 1 bet.
Makes absolutely sense and I think you are exactly like myself, and actually for me, I do bet on sports very well, like frequently, But then, I am not really a fan of jumping from one casino to another, paying withdrawal fees to withdraw my money from one casino to another, since I am a type of person that don't like keeping multiple gambling budget, or let me just say that, I am not rich yet, so it's pretty hard for me to budget money for gambling in the amount that will be high enough to keep across different casinos.
So, I simply keep my gambling funds on one casino and do not withdraw from there unless I win a significant and withdrawable amount of money, else, I will just play there until my entire balance turns zero.
And Secondly, like you've said, I also don't do high roller betting, the money I bet on sports are usually small amount of money, in the sense that, even if there is an odd difference between casinos, chasing that won't make any much or noticeable difference since the amount I use to bet is not high enough.
So, I simply just stick with and on the casino Ive initially choosen to play on.
