When I started fly fishing as a little kid my dad didn't see the difference between tippet with that X and regular fishing mono.
Years later I gave up caring about that as well and now buy 100 yard spools of flouro for something like $5. I usually carry 10,8,6,4 on me and a spool of 7x.
I dont think to this point I have ever caught less fish because of this approach. And now I dont cringe when I have to rebuild a leader like I used to when I was buying those 30 yard spools of expensive tippet, or premade leaders.
