I own probably 40 Pheil carving tools. But, the old 80/20 rule really holds true with these also. I use 20% of them, 80% of the time. I use the 5 mm wide, in 1,2,3 and 5 profiles most of the time. 5/2 being the most used of them all, I have 2. I would suggest looking at these numbers and build from there. You can use a stamping tool, like used for carving, to cut-in your tighter curves for inlets rather than gouges, or make some of the tighter radius tool you might need.
