I got the Southwest cue and it unbelievable in person.  Makes my heart flutter.
Fast and loose.
As far as the Kers -
It lookes EXACTLY like that cue.  I hit some balls with it and it feels great...and I do mean great.  The shaft is 13mm or very close.  I was not interested in the cue, but my buddy here in town was considering it.
As far as the weight, I did not measure it but if Greg says it is 17.5 oz I believe him as it felt balanced and i could tell it was a sidgin less than I play with, (around 19) it did NOT take away from the cue.
Greg told me that Laurie told him for sure it was a KERS, and would back it up with the letter.  I told Greg, the if was me, I'd get the letter to eliminate any issues or questions.
I dont have a dog in this hunt, but I thought I would pass on my thoughts to my friends here.
