Threw the R-Pro Vulcan today. Seems WAY less stable to me than the Star Vulcan. I WAS able to throw it though and even use it for a couple helix shots. Bested about 340ft with, which is the best I can do as of yet. Think it will stay in my bag until it hits one to many trees.
The R-Pro is VERY flippy. I shouldn't be trying to throw a 13 speed driver. I am just handling 10 speed drivers fairly well and hitting 300ft fairly consistently. I turned it over on multiple occasions today, but it did give GREAT distance.
