I hate stacking off with a 200BB effective stack unless I have the monsta nuts. With 100BB effective stacks I've found it's a lot easier to take advantage of the villians who are looking to double up against you.

And like RML said, it's situational.

And don't let it bug you if someone calls you a BR nit for being overrolled. BR management is all about helping you play your best. There are some good guidlines that should be obeyed, but there is no 'one size fits all' rule.
