I would say the majority of the tighter feel is due to the bushings. The OEM bushings have an inner piece made of firm rubber but it supposedly wears / elongates as it ages. Has to cause the shifter of get sloppy over time. The OEM triangle piece is held in place by a plastic pin that probably also wears out over time. The Function-First triangle piece uses a metal pin which would reduce the chance of wear.

If you already have the bushings changed out, you probably have the majority of the fix.
