Looking for a strap to keep my neck heavy guitar from sliding to a perpendicular (sometimes even below) level while I'm trying to play standing up. I've only been playing for about 7 months, so all I have is just a basic starter strap that I got with my basic starter guitar so I wouldn't be out too much if I didn't care for guitarist things.

From looking around, it seems like a wide suede strap is the best solution, so I was thinking about going with one of these baddies (they look pretty slick as well.) http://italiastraps.com/guitar-straps-uk.html

Any thoughts on them? Something else you might recommend? Thanks for the advice!
