3x tippet for bass?
If I were tying a tapered leader for bass (or any warm water species) I'd probably do a 20 > 15 > 8 pound mono (0.11 diameter = 0x) or even 10-12 pound mono.
3x tippet works to about 0.08 dia = 4 pound test. This is FAR smaller than is necessary for this target. I definitely take your word for it and I'm sure you've had plenty of success with it, but have you considered increasing your tippet size just to experiment? Shoot, I'll fish 8-10 pound mono along all kinds of snags on the bottom without worry
The abrasion resistance you get going from 4x to 3x is nothing compared to what you'd get going from 3x to 8-10 pound mono!
