I've used Maxima UG for the last 15 years, but because of my recent experience in getting a couple batches of poor quality line (15lb test UG breaking at 10lbs -fresh out of the box) I've switched to trilene XT. I agree with Tule's post, At the same test XT has a thinner diameter but a higher breaking strength than Maxima UG. If you don't believe it, test it for yourself. Try tying a piece of trilene xt 14lb to one end of a swivel and a piece of 15lb UG to the other and pull. Although the UG is considerably thicker, it breaks first every time.
