[SAHTT]

I'm getting a new helmet. I currently have two size M Shoei's, one beat to hell and one about half way there. They are both TZ series [currently called the TZ-R].

I'm planning on getting the RF-1000, size M, if I get another Shoei. I remember my last shoei fitting nice and tight when I first got it, but it's definitely slightly looser than I'd prefer 3.5 years of daily riding later. My older tz is even looser.

There is no way I can fit in to a size smaller than M with shoei, but I'm wondering if other people have a Suomy or Arai in size M as well as a shoei and can relate their sizing. The only semi-local place that allows you to try on helmets doesn't have much of a selection of higher end units.

I've heard Suomy fits a little tighter in general. I know their are head shapes, padding, etc. to consider but mine is typically considerd "normal" and I'm limited to the

Shoei RF-1000
Arai Vector
Suomy S1R (??)

All solid colors FYI pricing wise. 400+/- is good. Any advice? I'm going to end up defaulting to the RF pretty soon but feel like I might be missing out.
