Which Green fighter to invest in? My best are...

SP SS Goku - (lv. 1000)
SP Super Trunks - (lv. 1000)
SP Mai - (lv. 600)
EX Gohan - (lv. 1000)
EX SS Trunks (Teen) - (lv. 211)

I have others as well but I'm focusing on Saiyan/Super Saiyan/Hybrid Saiyan tags primarily.

Wondering if I should wait until I get SP Vegeta or SP SS Cabba, or if I should press forward with what I have? Any thoughts would be appreciated!
