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 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.
