Good job, Mike.
1. A straight razor is a natuarally more aggressive on your skin than a disposable and you can expect to feel a little raw after shaving for about the first two weeks. try to give your face a rest and shave only every other day till you adjust.
2. You could also be using the pressure of the Trak II shave which is unnecessary and will amplify any bad sensations try letting up on the pressure.
3. The shaving angle may also be contributing to a razed sensation. try to keep it below 30º.
4. Finally having an unstropped blade at your whiskers isn't an ideal situation. Even if Bob stropped it before he put it in the mail, it only takes about 24 hours for the effects of the stropping to be lost as the steel reforms to its memory of having come off the hone. Time for you to strop that little darlin'. Go slow and easy with very light pressure and try to feel every nuance of sensation throughout each stroke. 30-60 laps up and back and be careful not to lift the spine or drag the blade off the edge of the strop.
It's all down hill from here.
