Poly Locs or Mag Mounts?

I installed the larger PST 1.03" torsion bars last summer and I have some rattling from the header on the bar. I installed a torque strap which helped, but I still get some rattle. I was thinking of ditching the stock rubber mounts and either installing the Mag Mounts from Mancini's or the Poly Locs. Huge difference in price, but Im unsure how well the Mag Mounts work and if I will be happy with them.
