I finally got my Guts Tall Medium density foam and cover installed. Don't let anyone fool you, there is a sizable difference in height, and a very noticeable difference with the Med. density foam vs stock. The foam is much firmer than the gushy stock piece and you sit a lot higher (I can only tiptoe both feet now). The transition from standing to sitting should be easier, but those off camber hills and my short legs may not get along as good with the higher stance. The firmer foam feels better than the stock to me. I never really got used to sitting down "in" the bike and that gushy seat would wear my butt out. The green/black cover looks better too.
