What record weight for Rega RP10

I have the RP10 and not sure whether the bearing on this table is even designed to work with or can accept the load of a record weight. I have a the ClearAudio clamp but can hear no discernible advantage with it, plus I am concerned about applying pressure to the bearing when using it. There so many record weights available and I am just a little cautious as I have called The Sound Organization but haven’t been able to reach anyone willing to provide an answer.

So has anyone with a Rega table found a record clamp that works well with your table? 
 

Thank you in advance
