JR SPEY, great post!
That's exactly what I was looking for.
It sounds like you have the same casting style as I have. I don't like to waste any casts just 1 backcast and let it go on the forward cast. I had already bought an intermediate 11/12 Airflo Beach line 2 weeks ago that was on sale. I will try it when I get the rod and if I find the same problem you had I will get the 9/10 version from the same place. I also bought a 12wt Outbound (long head) floater and will see how that works.
I can't wait to use this rod around Montauk Point this year.
