I just picked up an XP 9' 4wt. I'm trying to decide which line to get for it. I seem to be torn between Rio Grand, Rio Selective Trout, SA Trout, or SA XPS. The reasons I purchased this fast action rod was for longer casting with delicacy. I've always used DT's, but I figure a WF would be the way to go, taper wise. As to the delicacy issue, I will be primarily using this rod for longer distance dry fly fishing over spooky fish, so this makes me wonder about the heavier Rio Grand taper.

There is no fly shop nearby for me to take the rod and practice cast the different types of lines. Any experience and suggestions would be appreciated. Thanks in advance.
