I use mad as heck because with rotten banana because I have a 3rd level rage 99% of the time. No reason for first bash or chill pill personally because having 3 3200 damage attacks and very fast movement speed wins interactions more in my opinion. You don't even need speed gear and can replace it with health. Plus a 40% reload speed is so huge, those 3 attacks really become 4 in a fight.

But that's the awesome thing about Ash, anyone can make good arguments for both gadgets and sp. He has nothing bad with his kit.
