ZVZ 2 base 1/1 roach timing attack

Hi, I'm looking for a ZvZ 2 base roach timing attack with 1/1 upgrades that hits right before or when the spire completes. I've searched a lot on the internet for a build like this but all I've come across are old roach rushes that only worked in the early months of Wings of Liberty. Can anyone post either a link to a build like this or write one down for me? I'll really appreciate your help!
