I normally use FD-UR#3 and #5 and #7, lately I have been cutting more detailed cuttings and I want to order some new blades. I like the FD-UR#3, but was going to order some smaller blades, what I was wondering is the difference between the FD-UR#1 and the FD-SR 2/0, I see they both use the same drill size, will one cut tighter turns than the other. I am not that familiar with the smaller blade sizes. What would you recommend for cutting portrait style patterns. I generally stack cut 2 or 3 1/4" pieces. Spirals are not an option, I tried them when I first started and never liked them.
