I'm doing the same thing you're thinking of. Stock front on my '07 Softail Custom is a 80/90 21 (MH90-21). I went a size up with Pirelli Night Dragons 90/90 21. I read lots of good things about the Night Dragons so I went with them instead of Metzlers (which I have on my other bike). They just came in today so I can't say anything about how they are yet.
I was a little concerned if the 90/90 would fit but I'm almost certain it will. If not, oh well, I'll order another. I went a size up because wanted to experiment and see if it makes any difference. At best it'll ride a little better than the 80/90....more contact patch, trail better etc. At worse, it'll rub against my front fender. LOL
As far as the Metzler questions you have. It'll say on the sidewall where they're made. the ones I have on my Dyna are made in Brazil. I got about 4k on them, I think. No problems other than my front does't hold air like it should. Not sure if it has anything to do with the fact that they're made in Brazil, but they do lose about 2 psi in a 24 hour period. My rear tire doesn't. Other then that I'm happy with the Metzlers.
Are you running stock Dunlops now? Remember, tires may slightly vary in size (width/height) depending on the manufacturer. The Pirelli 90/90 I ordered is as tall as my stock 80/90 dunlop. The Pirelli 80/90 would have been shorter. You can always email the manufacturer and get the specs.

Can't help you with the Avons. I never ran them.
Good luck.
Have over 100k running a 90/90-21 on the front of my 07 FXST. No problems so far.
