Those look nice. I used the K-Tool international KTI70081, same as Eastwood Professional. It makes nice flares, but needs to be vice mounted. For a few bucks more the mastercool listed is much more portable.

I'll have to look at those lapping tools. I have two of the stainless brake lines that don't want to seal well, and there were the pre-made lines from Right Stuff. The lines I made sealed just fine.
