Thank you all for your feedback. I may have gotten the 2006 model wrong, he told me over the phone when I was sick in bed... I'm going to see the bike tomorrow. I would prefer a 2008 4.5 but can't find one big enough.

I tried a 53 Fuji for size and it was definitely too small, so I'm still thinking 56/57... but I don't know if its too big/small until I try one...
