B44.3 centre diff or slipper ???

[Dkfream]

Sorry if this question has been asked before, just bought a B44.3 and waiting for it to turn up, I will mainly use on carpet and slippy gym floor, what is best centre diff or slipper, also would I just order a slipper assembly for a b44.2 to replace the diff and would that go straight in, also what diff oils would be best for my needs, running a B5m ATM so not sure on which way to go
Any advice would be appreciated and thanks in advance
