If your casting a SKAGIT line with your rod then put the RIO set away and buy Skagit Master #1. Skagit casting is a lot more compact and slower than casting a mid belly line, you also use more bottom hand to apply power rather than the push/pull of casting longer lines. There is enough difference between them you may find yourself frustrated trying to learn to cast a skagit line using mid belly tactics.
What you could do however is get yourself a "switch" line. These have longer heads and will allow you to learn the traditional style casting as opposed to the compact style of skagit.
You could also go back and trade in the switch for a true spey rod. This will also help because it is designed to do what you want. Casting strokes need to be adjusted when using switch for skagit casts. A switch also cant toss heavy sink tips and large flies as easily or as well as a proper spey rod. I used an 8wt switch for an entire season for steelhead and by the end of the season I sold it to buy a proper spey rod because I felt I was working too hard at times trying to use what I wanted instead of using what the tackle could handle
Personally I love my switch rods, for smaller systems, when I don't need to cast too far, need to use big flies or heavy tips. They really shine using Scandi heads with/without light to medium sink tips. Upside is you can still cast some pretty gnarly flies with them. Like a 4" bunny for Bull trout with ease
