Why don't you just try each one of them, which ever one sounds best to you you leave in, till you want something different, then do it again :-)
I use a Denon Dl-S1 (7 grams) with my ET2 arm no problem, I have used the Carnegie One for years (it is an old cartridge).
The ET2 lists cartrides from 7 to 15 grams. I would stay at 7 to 12 grams. they list it's complinace is from 7 to 20.
The heavery the catridge the more weights, you will have to put on. They recommened that the weigh stay between the 3 and the 6 on bar scale for best rsults.
