Well, assuming everything else is equal, you are going to make way more gains on test alone then anavar alone. I'm not saying anavar is bad, because it isn't, but it doesn't come close to test for mass/strength gains. Also, you could run a cycle of test for half of what a cycle of var would cost you.
As for losing most of it this just shouldn't be the case. If your PCT is in check you will lose some of it, but you shouldn't lose most of it.
I should add, I am not against the short cycle either. I think it has it's place as do the longer cycles.
