LA318 Pistons for performance build????

Hi Guys,
Can anyone tell me what would be the best piston for a performance 318 build?
Hyper's or Forged and what is on the market these days?

I have done a little sniffing around for a forged piston but TRW seem to be the only option but the comp is not great and they seem a tad heavy compared to the KB's!

Thanks in advance.
