Which one to R5.

F317

I want to R5 one of my *5, between SSE (duped) or CAIW (unduped).
My other 5* R5 are Medusa duped and Domino duped.
I don't have Blade or GR as 5* (for SSE Synergy).
Need advice guys. Thx a lot.

Caiw needs his sig badly but sse dosent. Look out for a science ag and if you can grab it from the rifts then take capiw to r5. For now, SSE is a pretty good option. Btw,most people call sse sparky.
