I think a longer rod will be easier for you to fish in water like that. I own that 6' 3wt Grigg, and while it is a kick to fish on small water, it is not a rod I normally select for most fishing, even though I live with a 3wt in hand.

And Grigg is a definite entry-level or behind-the-seat rod, with components you would imagine for a $30-$40 rod. But they fish just fine, IMO.
