I can't give any advice on high performance folders, as I ride a Dahon Curve (with a million upgrades), so I defer to my friends here on the forum, but I'm glad you are reconsidering small wheels. Once you get over the idea that these bikes are "weird," you can really enjoy what they bring to your riding experience.
Someone referred to me as capricious when I was questioning how they handle the strange looks and the attitude towards my clown bike. I wish I remembered who, because I'd thank them for setting me straight. I ride small wheel because I love it.
Think of it as adding to your resume of bike riding and owning experiences!
