Its all subjective!!!!
One mans "That thing beat the hell out of me!" is another mans "That thing was badassed!!!".
I like a little roughness myself but smooth woodies like thunderhead and Kentucky Rumbler are like heaven while TOO rough woodies and even some steel coasters are pure hell! However there are alot of people that would disagree with me when I say The Scream Machine at SFOG is a bone crushing monster. Why?
ITS ALL SUBJECTIVE!
Like art, music, and even brussel sprouts!
