You can have too much CW as well and not enough shaft. I wouldn’t recommend having your counterweights pushed hard against to mount end either as you need a bit of play , they do flex a couple of mm

My 2 cents ......
Right now I use 2x 5.1kg counterweights on the EQ6-R with both pushed right to the end of the (non-extended) shaft. To balance East Heavy I can slide up one counterweight about 1cm for imaging on the western side of the meridian, and to balance east heavy for the eastern side of the meridian I need to use the extension shaft.

Total payload is approx 13kg. So 3x 5.1kg CWs pushed quite far up the shaft may work better from a moment arm perspective? Hard to say without a weight to try with
