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.

Actually, it's always best to keep the counterweight as close to the pivot point as possible. If it's really far back on the end stub, you might want to add the extra 2 grams at the cartridge end. If the counterweight is half or more in, I'd just leave it.

It sounds fine to me, but its my first turntable and the only reference I have is various shop setups I've heard. The counterweight is quite close to the pivot point, so I guess that is ok too. Wouldn't adding the extra weight push the counterweight further back rather than forward?

Also, I'm not sure what "Also make sure with the weights at the cart end that you accomadated the VTA for the extra mounting height." means.

I'm sure I will start to obsess about how it could be better in time, but for now I'm satisfied. I don't have my regular CD player, a Wadia 850, hooked up yet (I have moved, so it is in a different continent :) So, for comparison I only have an ipod with a Wadia dock set up using the analog output. If the turntable weren't able to beat the ipod's DAC I would have demanded an immediate refund :)
