Wilkinson compensated saddles

Anyone tried the Wilkinson bridge with compensated saddles that are in the Stewart-McDonald on-line catalog?

...with the swivelling saddles, I will be getting a set this coming year, having had them demonstrated to me by Trev Wilkinson. I reckon they would be an excellent solution. I tried the standard StewMacs, and while they did the job, after some modification, they made the guitar sound bad. Just my guitar, mind. Others here have had great results with them, and for the price, they're unbeatable, if they work for you.

I just had them put on by Dan Erlewine. It was a Kubicki
neck to a Warmouth body.Both 15 yrs.old. I have a problem because the saddles needed to go back so far
to intonate properly that the oval head bridge plate screws are in the way i.e. the height adjusting screws
ride up on the b.p. screws! I like the ability to intonate
as perfectly as possible,but I now need to find FLATHEAD SCREWS for the b.p. What makes it worse is Dan cut off
the height adjusting screws so they wouldn't protrude,so
if I find FLATHEAD SCREWS I'll have to get new h.a. screws too. I'm disappointed that I had to learn this,and
after the fact!!! ALSO in tilting the E/A barrel to intonate
properly it throws the A string out of alignment(towards
the center of the neck). So the string doesn't cut the
center of the 12th fret dot,but the inside of it. That's because the barrel has a high straight center section which is off at an angle when turned for intonation. I'm
disappointed in the lack of Research and Development
by Wilkinson, and Dan Erlewine's not notifying me of how
it was not lining up simply.

P.S. Anyone know where I can get FLATHEAD SCREWS?
