I play a lot of serve and volley. I suggest you try natural gut mains with synthetic gut crosses. If you use the lower prices guts, it's about the same cost per racquet as premium multis, and plays better and lasts longer, in my experience.
Otherwise, go with a good multi. Most polys aren't good in the touch department, but Big Banger Ace is OK. Compared to a gut hybrid, or a multi, it's harsher on the arm.
