You'd have to ask a Linn person about the weight, but I use a Ruby 2 with my LP12 and Ekos and I think it sounds great. I do have issues with my anti-skate, but I think my problem is that the Ekos' adjustment knob is not calibrated correctly on my unit. I don't have any tracking problems at all. I upgraded from the Benz Glider and it was a noticable improvement. More details and information, but still as musical. If you liked the Glider you will like the Ruby.
I've also read a gillion great things about Shelter cartridges, but I'm not sure if they make a good match for our combo.
