if you wan comfort and stable (reasonable) drive, go for KaYaBa's absorber. APM had shown decrease in their build quality recently. Temporally dun go for monroe, for i had received a lot of complain on it's sensa-track and reflex type absorber. Earlier one didn't make through 3 months on our road and later one didn't make through 9. So far so good, Kayaba seems to be the most reasonable absorber for it's price range.
reminder: if you wan to upgrade to 1.6, you need to change it's spring and spring cap as well.
