So…you’re close to me. Here’s what you want to say - and it WILL vary from person to person regarding what you get so try to find someone you like and stay with them (or a few of them).
“Number two, sides and back. Blended in tight. Cut the top down so it just falls back - not spiked, just falling back.”
The “just falls back, close to spiked” is the key length thing for the top. Also, them thinning the side to blend in better is a good thing and will make it look better longer.
