This, absolutely.A $1200 rod will not make you cast any better but a $30 rod will make you quit fly fishing. lol
The Flex is a great rod, I've played around with one. But, go to a shop and CAST some rods. Also consider what your primary fishing method will be with the rod-nymphing, dries, streamers, general purpose, etc., because that may have some bearing on your final choice as well.
