TWL Weight Mod question

I have put a couple of lead fishing weights on a Rega arm with an Ortofon VMS 20E Mk11 cartridge,it sounds great except that it has a low cartridge resonance-around 7 Hz,should I persist or desist with this?

I don't believe 7 Hz warps or footfalls are particularly common. If you want to raise the RF slightly you could try some lower mass weights. Otherwise, if it sounds better with the weights than without, I'd say enjoy.

I am confused by one thing though. You originally said you had a RF of ~7Hz. Now you say it's ~12Hz. What has changed to cause such a large shift? Adding the paper clip shouldn't do that.
