Welcome to SRP Robin. Straight shaving will come with a bunch of challenges & starting with a kamisori or non folding razor as you called it may not be any more difficult for you than a regular straight... or it may. I found it took me a handful of shaves to adapt to one but I had been using regular straights a long time first. Starting from a clean slate with few preconceptions you may well learn easily. Keep us posted on your decision.
