This is just my opinion but assuming money doesn't matter there are two string options, poly and natural gut. Everything else (multis, syn gut etc....) is pointless.
Gut is the best for power, feel, pocketing tension maintenance.
Poly is the best for spin and some would say "control".
My rule of thumb is if you are anything but a very heavy spin player than nothing compares to gut/ poly hybrid with gut in the mains. For the poly I like smooth/slippery co-polys.
Really once you try these I highly doubt you will go back to multi or syn gut- AGAIN, this is unless cost is a big issue for you. If it is, don't try this setup because I don't honestly see you going back once you give this a try.
