One factor not yet specified is bar width. High trail bikes want wider bars, for "leverage" as one poster above puts it. Low trail you don't need or want leverage. It's more about letting the bike go and less about making it respond.
Also want to say the rearward position of saddle is just fine. With a lot of years and a lot of miles behind me I can remember decades when everyone automatically shoved the saddle as far back as it would go. Everyone from the pros to the guy assembling bikes in back of the LBS. Don't recall any breakage. Mine have always been all the way back and no problems ever.
