Well gents, It arrived today and I already had my first shave with it on a feather pro.
It is a hefty razor and will shave just on it own weight which I like in a razor. The blade alignment is perfect even if there is a little play in the head when not tight, but It holds the blade securely. This little head play is due to the round hole which the bottom plate goes through the top plate being a little wider than the post. Having said that, though, I'm sure Brian did this for a reason, presumably to assist for easier assembly.
The shave is exceptional, 2 passes with a bit of correction and I got a BBs. It is however a bit more aggressive than I like with the pro and next shave I'll try the guard or the MG. With these blades I'm sure it will be perfect. One word of caution. The angle is not intuitive and has to be mastered.
On the first stroke I used the same angle I use with the general and it was too aggressive. The moment I changed it to a shallower angle it began to sing to me.
