So been shaving with a DE razor for a few weeks and starting to get the hang of it, after the initial razor burn from the wrong angle. My only worry is that I should spend more time with the DE razor before trying a shavette razor, or should this not worry me? If so what shavette razor should I use as to start with?

The only reason I am considering a change is I had a barber shave today and they were using a shavette razor, and the shave was very smooth (although I had to go over two small bits with my DE) I'll be going back as I forgot to ask what oil base product they used at the start and finish, as after the shave I coudl feel a little razor burn which then vanished with this oil product.
