Sufix Invisline Castable Fluoro

I have tried a lot of fluoros and hated everyone of them. I recently purchased Sufix Invisline fluoro and spooled it on my Orra SX spinning reel. Here in Illinois the weather has been low 50s- high 40s. So today i went out to the local river to do some casting and test out the jigs i have tied this winter. This fluoro is by far the best i have used. Casted like a charm and had no problems. As with most fluoros, i was worried about knot strength. I had a snag and it took A LOT for me to break 8lb test. I am going to purchase a spool of 14 lb test to put on one of my Revos. Thanks Sufix
