Application is moving coil stepup. Want to make the classic Leach common base circuit but with modern quiet FETs.

I'm shopping for the P channel first as it's far scarcer. So far I've found the LSJ74 which looks good but as usual noise shopping is an uncertain science. What JFET pair would you use for small signal jobs and specifically for this circuit? Thanks much...
