Question: is the rod better suited to 6 wt line or is my poor casting letting me down with the 5 wt line?
I have the same rod and I use a Rio Gold 5 wt. line on it most of the time; sometimes an SA Sharkskin 5 wt. It casts well for me with a WF5F line.
If you find it casts easier for you with a 6 wt. line, then try slowing down your casting stroke a little; give the rod time to load. You can almost always horse an over-lined rod into performance casting mode with a quick, fast stroke; just because of the extra weight of the line. If you slow your stroke down a bit with the 5 wt. line, you may notice that you can feel the rod load better; which sounds like what you're missing with your 5 wt. line now, but picking up with your friend's 6 wt. line.
Also, on your cast; both the forward cast and the back cast, once you can feel the rod load from the weight of the line, start your casting stroke slow and finish it fast. Some people use the exact opposite type of stroke and they're usually forced into horsing the rod to get their lines out where they want them.
One more thing. If you're relatively new to fly fishing, try not to drift your rod on your back cast; meaning, at the end of your casting stroke hold the rod in the position where you finished the stroke, don't let it drift back on you. That's a good way to miss the feeling of the rod when it's loading up with the weight of the line. Later on, drifting may become a friend to you when you want to make long casts, but for now, try to keep the rod in the position where you finished your backcast.
Give it a try; see if it helps your casting with the 5 wt. SA GPX line.
