Welcome!
I started with a shavette as well. I now have many straights but at least once a week still a shavette type (Feather RG). I find the best angle (for me), is close to flat against my face with just enough pressure to scrape the lather away. Also making sure to use short confident strokes. If that's not enough to concentrate on...I find stretching the skin tight also makes life a breeze. Doing all this gives me a very close 2 pass shave with no irritation.
Now that shaving is enjoyable you can take your time and practice as opposed to rushing through an otherwise mundane chore :)
Cheers!
