I think, like most things in poker, it depends.
(1)If you have been playing well and your not taking money from your hungry children (money that is surplus, ie dont play with scared money - if that make sense) then you reload with what money is surplus.
(2)If it is money you cant spare, then freerolls it is.
However, i would advocate a little sit out period, whare a review of the
hands you lost out on takes place and see if there was a major leak there. if it was just being donked on then return playing either freerolls or reload depending on financial situation.
So for me it depends,
I wouldnt fancy building a bankroll through freerolls if i have surplus money to invest and rebuild my bankroll- especially if i know i was playing well and just got donked on.
If i dont have surplus money i have no choice but to freeroll it!
