I would consider myself a line 2 surfer at this point, actively looking for opportunities to practice bottom turns and connecting them with cut backs.  I do feel that I struggle with the concept or feeling of riding the rails.  And as a surf enthusiast, I'm intrigued by all board shapes and sizes.  I currently ride a 7 footer pin tail mid-length mostly.  Would riding a smaller fish help or hurt the process of learning to ride the rail more?  Thoughts?
