"I think I get red-flagged by the the USGA because I'm always trying to walk that fine line."

I'm not sure if this is an appeal to the putter collectors and a way to get attention, but PGATour.com's Mike McCallister talks to Scotty Cameron about his putters and gets these two interesting quotes:

"I think I get red-flagged by the the USGA because I'm always trying to walk that fine line. I think if you're to buy my products, you want me to be on the edge, you want me to be barely legal. But if I'm well within the zone, then it's like we're not stretching the limits enough."

And...

"People say there's no arc in the putter stroke. Well, is there an arc in a golf swing? Of course there is. ... There is an arc in the putter stroke. I wish there wasn't. But there is -- it comes from the lie angle of the shaft. The USGA says its must be at least 10 percent, not straight up and down. With that angle, there must be an arc. ... I wish we could putt between our legs, 90 degrees, square to square. But the USGA says we can't putt between our legs, so I design putters to fit those arcs so that it becomes almost effortless for the putter."
