your right. actually all of my sujis flex a lil bit. but its not like i use this flex in any way. even the zakuri is not 100% stiff.I'm curious what Sujis you guys are using that have no flex? Only one I've tried with zero flex is the Kato workhorse from Maksim. All others have had some flex. I'd prefer a thinner tip than stiffness, but I'd like to hear others opinions.
