Welcome to SRD! There are quite a few of us that come from a technical background so no worries there. Good call starting with a shavette. I still think that it is one of the better ways to enter this hobby. I still have my in my travel kit and will take it with me if I don't want to risk TSA issues or having a nice razor/equipment lost or damaged.

Let us know how the shaves are progressing with the straight.
