In the latest issue of Tennis Magazine there is an ad for the Yonex RDX 500. Anyone bother to read it? I did. Now, I don't know whether I can respect tennis brands anymore. First, the ad mentions "Memory Titanium" which has double the restitution force of ordinary graphite. Then it mentions "Super Metal." Yes, Super Metal. My problem is with the wording itself. For all I know, Liquid Metal, HyperCarbon, and this Super Metal might actually do what they are supposed to, I'm no scientist I have no idea. But why in the world do they come up with these cheesy names for the actual materials? A gimmick is supposed to make me want to buy the product, not think that is is some kind of con.
