It's 6061 aluminum that all the companies are using...
Really? Mathews uses 7075. I know Hoyt uses 7075 for at least some of their bows. I figured that other companies must use the same materials, since the prices aren't that different. Hmmm... Since 7075 transmits vibration a bit better, maybe other companies' bows wouldn't be shootable with anything other than 6061. Must be why there are so many bent risers.
Anyway, you're right. There have been technological advances over the past 20 years. But the advances in materials are not proprietary to any bow company. Your manufacturer doesn't have anything the other companies don't have... except a really wild way of trying to claw their way back into some market share.
I think we should change the title of this post to "The Quicksilver and Arthur P Debate"
There ya go! Good idea.
