I have 110k crys right now, but I will have 140k by the sale. I have isida m2, rail m1, smoky m1, twins m1. My hulls are viking m1 and hornet m2. I already plan to get m2 smoky, but i will have 80k crys left over. What should i get?

Should i get twins m2 or smoky m2? I am an attacker. The hulls I have are hornet m2 and viking m1 (but if u guys tell me to get twins m2 i have the crys to get viking to m2)

Guys, I have 80,453 cry right now and am not sure if i should get m2 thunder or m2 shaft or do something else entirely. Garage = m1 twins, m1 rail, m1 smoky, m1 mammoth, m2 isida, m2 hornet Fav map currently is Industrial zone

Would m1 rail be a good purchase for me? I have 48k cry and mainly use isida (m2)/hornet (m1) but I like to change sometimes and play w rail.
