I'm going for the Manual Transmission ZL1, I like being able to control my gears as if they were an extension of myself, I hear great things about the A10 but my 2 sports cars have been manual and I'm not sure I can give that up....not yet at least, maybe as my knee wears out but untill then I believe stick is the way to go, it's just a lot more fun to me.
All in all its your decision at the end of the day, good luck bro.
