Hey guys

I'm a low stake plo grinder and one thing(strategy?) I've been doing is leaving the plo zoom table when I reach 300bb and then reopen with just 100bb again so I can play optimally and not worry about getting exploited when up against other big stack. My question is, do you guys think that I'm missing out on a lot of potential +ev spots where I can win a 600bb pot or do you guys think its not that big of a deal? Because I use to be a tournament player and I know that having big stack (i.e. in a rebuy tournament, always rebuy) +ev but is it the same in cash game?

Thanks
