One of the joints on the 1300's cross link was very worn, so glad I ordered that as well. So both my cars now have the upgraded link. It makes the gear change feel surprisingly different, far more positive, but somehow notchy. I'm sure I'll soon warm to it, just odd after 14 years of Beta driving....
I suspect you're adjusting to the lack of vagueness that there is in the standard setup. The 'slop' in the standard bushes and crosslink has been removed and that's probably what makes it feel notchy.
