I've just had my final shave with the Alumigoose this evening and have a few other observations to add to my first post.
Firstly, the razor is definitely more aggressive than a stainless steel Mongoose (either B2 or B3). This has been a consistent factor with every blade I've tried. I would go as far to say that a Kai Captain Mild feels very slightly more aggressive in this razor than a Feather Pro Super does in a standard Mongoose.
Secondly, in my experience, I prefer using it with Kai blades. I didn't notice much difference between Kai Captain and Kai Captain Mild blades when using the razor. They definitely gave a smoother shave than Feather Pro or Super blades though.
Finally, I tried a combination of differing handles (both long and short) and found that a longer handle suits the razor nicely (I settled on a UFO Kaiser 100mm as being the best combination with this head, closely followed a standard Mongoose stainless B2 handle). I found that it was not so much the weight of the head that was the major factor in this choice, but the width of the head. I reckon that this head would pair well with a long Titanium handle as well.
All-in-all, this is a nice razor which, if you find the standard Mongoose to be too mild, is a viable and well made alternative.
The razor is now ready for packaging and will be on it's way to
@missingskin in the morning. Many thanks again to
@Holyzeus for the opportunity to try out this razor.
