I have seen test on the internet about mono being more abrasion resistant  than fluorocarbon can i get your professional opion on this matter

I don’t know that there is a big difference between mono and fluorocarbon - both superior to braid in terms of abrasion.  Although the line I choose for dock skipping and other rough edges is a co-poly (Yo-Zuri Hybrid).  Very happy with its abrasion resistance and knot strength when it counts.  

I believe that mono could be more abrasion resistant than Flourcarbon, however I have not seen the tests reflecting that.  I will say that I have gone to exclusively fluorocarbon and braided line (65% F and 35% and very rarely do I use mono unless it’s as a leader in front of braid for top water.  To me the advantages of fluorocarbon far out reach outweigh that is Moana. The sensitivity, invisibility, lack of stretch and performance overall make it a clear choice for my presentations.
