Rega P7 + Dynavector DV20X HO

Maybe you can add weight to the one you already have? I'm pondering doing the same. With a 20XL on my RB300 the counterweight is all the way back. I'm wondering if a heavier one closer to the pivot would be better.

If I ever find time, I might drill and tap some holes on the sides of the weight. That way I can bolt some brass or something right to it. Seems to me it is best to spread the mass to the sides, thus increasing lateral dynamic inertia without affecting the vertical.

I have decided to get the Rega heavy weight - a larger version of the tungsten weight. It is best to have the counter weight closer to the pivot point.

You seem to have a good idea - be very careful on your tapping holes on the side. They will need to be exactly 180° opposite of each other or you may induce some skating into the tonearm.
