2/2 is kinda unnecessary but 2/0 roaches rape shit and can come out pretty quick if you start +1 early enough, a good timing to hit is lair around 7 30, grab a few gases, make a 2nd roach warren, when lair pops start +2, speed, burrow, burrow movement, then make maass roach of like 60 drones, works pretty well against most shit if you got good macro.
If you are finding you have too much gas either:
Take the gases later
Take less Geysers,
Play around with when you take ur 3/4 geyser,
Take guys off geysers when you got the gas you need.
Generally a good timing is 2 gases at 6:00, ling speed with first 100 gas, roach warren/evo down round 7:30, start lair with next 100 gas, take 3rd gas, start +1 attack, take 4th/5th gas depending.
