Question on mud tyres

I was talking to a couple of friends of mine, my BFG Mud Terrains have done 50 000 km and are a little old, I told them that I would get something like a set of Simex's Centipedes and use them on weekends and all terrains during the week but I live in an area of Victoria with heaps of bush tracks even beside my property and I don't know two weeks in advance when I'm going out like most do, I only know five minutes so I can't go down the pathway of changing my tyres before and after every trip and I get people knocking on my door who are stuck nearby and need help, they taught me two ways around it that I'm curious about.
1. Put the same amount of money weekend Simex's and all terrains would cost towards my mud terrains (or any all round mud tyre), every year at the start of winter get a new set and sell my basically new ones for about 5-6 hundred dollars and always have brand new ones on, they say they'd probably be just as good in the mud, better on rocks and nearly as good as all terrains on the road and in the sand, best of both worlds, no changing my tyres, rotating them and little balancing.
2. Get all round mud tyres and beadlocks and run them at about ten PSI when I need to and they'd have two or three times the footprint Centipedes get and be just as good in the mud, way better on rocks and heaps better on the road and in the sand and it would be cheaper for me in the long run and I'd have beadlocks.
Do people think this would work for me, anybody who's done it tell me.
