Hey Chuck,
The Arsenal Artillery is by far stronger than the Heat Blast. I don't have the Artillery anymore but I can tell you that when I did, I couldn't use it on carrydown that well. I switched to the Heat Blast and played a straighter line and found better success when carrydown came into play. As far as smoother, the Heat Blast is going to give you a smoother reaction naturally. Everybody that I can think of that has the Blast has said it is very smooth and doesn't overjump boards. Hope this helps some Chuck! God Bless You and have a great week!
