Thanks for the help everyone
I want to keep at Zerg and get better with them, but every time I watch a pro micro his marines amazingly or someone do amazing force fields I say I want to do that, but I also want to have the speed and the mobility of Zerg :\
FFs aren't -that- amazing in my opinion :P That said, you can do pseudo-FFs using Infested Terrans if you feel like you want to mess around a little (Destiny does it every now and then usually vs Thors and Ultras)
As for microing marines, well I suppose I can imagine the appeal of wanting to do it in a game, but there is a custom map which you can practise on called 'Marine Split Challenge' if that's enough to curb your interest!
