thank you to everyone that has responded, what got me concerned was the price.
i bought it for.......ready........with shipping 80.00
there is a SLDR that is not the S Model, But is a tour issue only. Tour heads do have a + sign on the hosel. Like this one.
tour only heads are going for upwards of $300.00 on ebay.
the other thing i have found was a video of Carl Pettersson and it shows his SLDR with the slider set exactly like this one.
here is a link
