I don't have a review of the G800 (not till I get my scanner to HiFi dave's anyway...), but the 820 needed around 3 grammes to track correctly, so therefore 2.7g seems fine and safe, with 1.75g for the 800E being ok too I'll bet.
I don't know when mine are coming, so I'll try to get another A70/Lab 80 headshell first, as I reckon the arm on this deck may be even massier than the Goldring Lenco GL75/78 arms.. Now all the balls are in situ on the main and tonearm bearing races, the deck is running very sweetly indeed and apart from a gentle throb from a slight flat on the still-soft idler tyre, the rumble seems more than low enough for good quality reproduction and I'm loving this deck to bits - thanks Adam :)
