I agree with the d2 setups. There is plenty of time for trait to come out and be safe, and let them roll, it makes no difference in zods eyes.
Just a thought
AK Pig Of The Hut at the point in your string that you do b23, can you instead get 213? The idea here is that you get the overhead in 213 forcing them to block high before the low lasers. If they block that high everytime you can do low lasers after 21 and hopefully get the hit. So what I'm thinking is that if this is blocked its pretty much the same amount of hits and time, however you get a 50/50 attempt before you spend the meter.
*Eh, I'm testing it now and the spacing gets harder. The range on b23 makes it work perfect every time. It might work well as a mixup though.
The coolest thing I'm finding about playing zod us that he gets 10x more fun to play when the opponent knows the strings and set ups. If people know this string and they respect all of it, that is going to open up chances for all kinds of other mixups that deviate from the original, like using 213, or throws, and other stuff.
I did find that you have plenty of time to do jump in 41, f2413, adding two more hits to this. I wasn't sure if you could get those in and still have time to use trait slash after bf3 but it works just fine.
