I use the cashout option almost every time.
I find the normal rake to be small enough that with the additional 1% 'tax' I can still profit over rake.
I have been on mad swings with AA vs KK and KK vs AA for example. I'd rather just lose 1% than having to psychologically dealing with such situations ^^
Most will tell you not to use cash-out, but personally: for 1% I think it's very beneficial to my mental state at the table.
If you CAN handle the $1000 swings to gain an additional $10 profit then cashout is not for you
