buying new 4wt advice

[surfdog]

I am looking to upgrade my 4wt fly rod and would appreciate some advice not from a sales rep. I currently am using entry level package rods from basspro.I cast well with them but am interested in a faster action. Winston offers a vsl in my price range but have not been able to find reviews.Also tfo has a few models. I'm thinking 9' 4pc any recommendations?
