Try something WAY weaker, and you'll like 'em fine.
I'm TOTALLY satisfied with my HG's which are somewhere in the X-100 (dynamic range). But, sometimes I have a student with Rifles and I want to demonstrate something. Like I said, I've tried all their flexes. Weak is horrible, stiff is less horrible, it doesn't matter. HG doesn't use Rifles, so it's of no consequence. HG also SST PURE's all of their shafts. I don't think there's another company in the market that goes that extra mile.
