Cartridge too light for counterweight?

I just purchased a Pro-ject 6 Perspex, and finally managed to get it up and running (no thanks to the horrible manual).

It came with two counterweights, the lightest one rated for 8-~ gram cartridges. The cartridge I got (Audio Technica AT33EV) only weighed 6.9 grams, but I was still able to balance the arm out with the light counterweight, and then had no problems dialing in 20 on the downforce scale (cart says 2.0g for recommended downforce).

After completing all the adjustments, I noticed a small bag containing a small weight (that I measured at 2 grams). It will fit over (or under) the cartridge mounting point on the arm.

Is there any point in adding this to bring the weight up, or is this just for cases where it is impossible to attain balance and then dial in the proper downforce using the supplied counterweights.

If you have acheived the correct settings, and it sounds as if you have. Don't add any more weight at the cartridge end tha necessary. The least amount of mass is best for tracking. Also make sure with the weights at the cart end that you accomadated the VTA for the extra mounting height.
I will be curious to see how you like your new table. I have looked at the RM10 but still ahven't decided to trade out of my current table yet.

In addition to MoFi's reply and to answer your question. VTA is Vertical Tracking Angle which is the relation of the centerline of the stylus to the groove plane. You can do a little research and experimentaion for your particular situation. But in short the angle can either enhance or muddy the bass line and at the same time effect the rest of the bandwidth. I have always felt that getting the bass as tight and acurate was the first priority. The rest falls into place. But fo now let your cartridge break in before you agonize over it too much.
