I suggest an Airflo Compact Skagit head. Here is a link to a chart that suggests the correct grain weight for your rod. As explained in the introduction to the suggestion is a starting point. The Chart suggests a 510 grain line for my rod. However, I use a 570 on my 13 ft 7 wt. as it is a very fast rod and the rivers I fish requires me to bomb a long cast at times.
