My V3 Starling was delivered today and I plan to try it out tomorrow.
It is a pretty heavy razor combination. I was too lazy to pull out a scale so I just compared the weights to other razors I have. The head feels in the ball park of my 2016 ATT SE1 head (which I find pretty heavy). The handle is also pretty heavy. I would say the handle (with the tip attached) is in the ball park of my Yates 3.25" stubby SS handle, my Rocnel SE-P handle (older version) and maybe not quite as heavy as my Stando King handle. Making the handle lighter may be one reason for the screw off tip (in addition to making the handle shorter). The threads seems a standard size so I could swap out for a lighter handle (or one of different length) if need be.
The machine marks make for an interesting texture on the base plates and don't detract from the razor like I feared they would. It has a nice feel to it.
I plan to give it a test run tomorrow if schedule allows. I am debating doing A/B shaves out of the gate (the V3 OC on one side of the face, MMOC on the other side for example). If I go that route, I would have to decide which razor to compare against the V3 SB. Maybe go with MMCP, MMBT or Blackand Sabre L2. If the SB turns out to be really efficient, then maybe a better comparison would be with the ER 1924 or 1914. Will see.
