on the issue of stacking two orals, i don't know that it's necessarily a bad idea, as long as you keep the total amount of drug taken to a reasonable amount.
for example, most people would probably use 50 - 100mg of winny stacked with an injectable. but if your doing a 40 mg ED anavar cycle (a low liver toxicity dose) why not stack 25 - 50 mg a day with that?
one advantage of taking moderate doses of two orals would be the ability to hit different recepters, without killing the liver.
that said, there are widely differing opinions. i'd be inclined to try a conservative anavar/winny or anavar/dbol cycle and watch liver function carefully, just to see how you react.
my 2 cents...
