I like the Rio Powerflex tippet material, but using Cortland Precision II 3X material left me wanting something with much better abrasion resistance. That Cortland really nicked up badly and quickly. The Berkley Vanish described as "the easy casting fluorocarbon" has had good knot strength for me and good abrassion resistance, but the advertised break strength for the diameter of line doesn't match very well. I wish that there was more of a standard in the industry. In very cheap lines they usually under rate the line because of the inconsistancies in diameter and they are covering their rear end when they quote a break strenth.

Like I said, just venting today,
