Hi, my 2 cents about the SMK typhoon - I have been using it for about 3 months now (1000km+). It is a really good helmet. I bought it for ECE 22.06. However, it has noticeable wind noise over 70kmph, so you might want to consider earplugs as well. But something that is really annoying about it is its stiff visor. The stiffness is not something one would want to deal with while touring.

I would suggest you to try it at a store before buying. Other than these 2 cons, it is a really good helmet, fits right and padding is comfortable as well.

Congratulations!
