hey man. the packman thing sounds fishy.
but the 540xd tour and 580xd tour should look the same other than the 580.

thats my 540xd tour. compare it for markings. i changed the xd and the r to silver cause it looks better so dont use that for comparison. but it should have these things to generally be legit
1. underlined half degree mark i.e. 9.5
2. a txxxxxx serial number
3. tp on the toe
4. completely different sole than the retail xd series
5. .335 hosel rather than .350
hope this helps man
