Replying to Mounting Question (Warden/Pivot)

So I just picked up a pair of blends that have warden 11’s center mounted… just started flipping but I normally keep my pivot/vishnu setup at 11 for rails. I’m thinking about throwing on a pair of pivots or attacks, but not sure if I can center mount twice or if there’s enough variation in the jigs. Also if anyone thinks I should keep the wardens on there, give me your arguments but otherwise I’m not sure they’ll be durable going forward & if I should just swap em now.
