Different situations require diff equipment and techniques.

I fished a jetti in Hyannisport this weekend. The weeds were on top and the stripers were down below - 6-10 feet. A floating line was about as usefull as you know whats on a bull. The sinking line was the only way to get the fly into the feeding zone.

As vehament as Abrames is about floaters there are striper guides in the northeast like Dan Marini who fish almost exclusively with heavy sinking lines and trust me the guy produces fish by the bushel. I have fished with him and gotten no hits on 5 straight casts. He tells me to wait 2 more seconds for the line to sink and bang - fish. Next cast wait 2 more seconds and bang another fish.

Again. Different situations - different equipment and techniques. There is no right or wrong. Only catching and not catching. If it isn't working switch things up.

That said I love casting floating lines because they are easy to control. Same can be said for intermediate lines. A blast to cast and still with pretty effective control.
