Sheeeeeeeeeeeeeeeeeeit.. This was dope as hell on both sides.. Both verses had a good flow.. Lines that stood out to me were..

Formula - Even Though Mines Was Tight - I Gotta Resist This
Move Rap To A Distance, One Positive I Must Dismiss. .
Is From My First Drop To Last My Ass Was Persistant

Masta C - My swings great but my stings late..i was a king..wait..
You can ring fate but I thought id do this till the day I die…
But I played a lie..Cause right now…I say good bye..
^^ Loved the flow !
