Switch MUDZILLAS for OL2S?

So I just acquired some barely used 28 S/W outlaw 2s on sti beadocks for really cheap
So my dilemma is switch out stock 28 mudzillas on my 650 xmr for these or not
I trail alot and mud along the way..the mudzillas are good for this Imo.
So I have the dbo 650 installed.id have to add rivets and secondary y/b spring and retune my mpt..I have all the clutch parts and auto tune and know how to do so but just wondering if the added weight and decreased ride is worth it..not to mention the havoc those tires might have on drive train..any thoughts or opinions appreciated
