I'll get the pictures and measurements requested either tomorrow or Monday.
I'll be honest, I don't really look at the size of the skate all that much; I look first for the holder. I have typically been on the smaller end of the 272mm holder. This held true for both the Peakspeed and the Jetspeed (271mm - I believe that is for the 8 and the 8.5). With both the CCM and the Grafs, before baking, my right big toe hit the cap. With the Grafs, my left big toe hit as well. So the Grafs do appear to be smaller, but it is pretty miniscule.
For sizing, Graf seems to have changed at some point, as I've been in a size 7.5 (270mm Tuuks, these are OLD) 707 and size 8 707 with 272 Cobras. I was also size 8 in the G75s (also 272).
EDIT: The struck out part was incorrect:
I had 707s made in Switzerland size 8 skates with 270mm Tuuks
I had 707s made in Canada, size 8.5 with 272mm Cobras. Both of these felt exactly the same size.
I've been in size 8 G75 and now Peakspeeds, and the sizing feels pretty close to identical; the Peakspeeds maybe slightly smaller.
