Good Bagseed stories?

Im into week 2 of flowering my first true grow, of which I resorted to unidentified bagseed for the endeavor. What Im wondering is, if anyone has had rather spectacular and surprising results from plain ol' bagseed? I am cheap, so most of what I had seedstock wise, is probably from questionable genetics. And I know that grow techniques in that 'realm' are even more questionable, resulting in seedy, less than peak thc weed. So have any people out there get dank, supercouch, mind numbing performance... out of seemingly plain random seeds?

I've seen a lot of amazing weed grown from shitty bagseed. There is a lot in the genetics, but even more in the care
