ducksterman,
At 4X, Seaguar & Enrico are almost neck and neck, 7.0 & 6.9 lbs. respectively. From 5X to 9X, Enrico really pulls away from the pack. For me, 5x thru 9x is where critical stuff happens. All 3x and above tippet material makers have a breaking strength that serves my purpose. YMMV. I do like to stay with the same brand for consistency or I will use a stiffer material (Maxima) for the butt section. It depends on what I am trying to achieve. You do have to watch the breaking strengths if mixing brands because your tippet could be stronger than the material used half way up the leader. I still don't see the need to buy fluorocarbon tippet material in the smaller diameters, unless your trying to get very small flies to sink faster without adding weight. Are there really significant advantages to justify the cost? Thanks.
Best regards, Dave S.
