The 314-2 is already a low deflection shaft so going to Revo or other low deflection carbon shaft really isn't going to be that different I wouldn't think Not surprised you didn't notice much.
Now try a solid traditional wood shaft and you'll definitely notice a difference compared to what you're used to. But Revo isn't massively different from a good low deflection wood shaft. Just has the advantage of not warping, no dings, etc.
I switched to a Revo from a Runde shaft with a micarta ferrule that I had built to 12mm. For a traditional wood shaft I always found it on the low deflection side but it's definitely not low deflection like the Revo. Took a bit to get used to. After the switch to Revo I ended up getting a SW Satin....and oh boy, that is a different thing altogether. It's a stout 13mm shaft and while it has a great hit it's definitely not low deflection, I literally had trouble making any shot with spin at first. Eventually over the course of an hour or so I was able to adapt somewhat but definitely didn't have the confidence I have with my Revo.
