Looking really sweet man, although I was in the market for a 3s PB
Can't make rift in PB, I was trying for Voice of Reason and a Gul ended up dropping for me before I found a 3s PB so I started hunting for 4s sceptors
Don't forget that trap laying speed is IAS and not FCR (just noted you mentioned FCR amus, pretty useless for a Sin unless you decide to go Eni IMO ^^)
Stay safe!
