Smp will suit you for sure,and they will blend it in perfectly as skalp are pros!!
Before I got smp done I never wanted to wet shave as I thought It would just look too flat etc I was always hoping that I can get away with 0.5 or 1 grade shave and I CAN , but smp just looks so much better when I wet shave 🪒 💪 ! So in regards to you concern that it would look flat- Smp is made to look better flat.
Hope this helps and good luck!!!
