I think we've now demonstrated that there as many different ways to set up a
checkstay as there are skippers. Mine is completely different but works
terrifically. I suspect Derek's system was forced upon the boat by the MORC
rules that prohibited checkstays led aft. Wilt's system also sounds like a
MORC compromise and I seriously doubt that a 4:1 block and tackle on the
genoa tracks can bring the right shape to the rig and tighten headstay
tension sufficiently to do anything worthwhile. All the other systems
sounded pretty good to me. Richard's sounded very creative, but if I
understand it the tail for the check has to be pretty long since it gets
dragged all the way over to the other board.
Here in SF many of us use a system based on Ed Durbin's IXXIS. The vectran check is held above the boom not by the typical shock cord off the backstay but by fiberglass poles lashed to the pushpit--lifters I guess they would be called. They're 3/8 inch 8 foot fiberglass rods fabricated from easily available materials to which is lashed a stainless eye at the top end. When there's no load on the checkstay the poles are upright and the lazy check is away and above the boom. As the check gets tensioned to a centerline block at the stern the glass rod bends down so the check runs straight. My system ends in a 30:1 winch on the deck at about the traveler. Works great. We don't pay a penalty under PHRF.

I should add that one additional advantage of my current set up is that I can calibrate checkstay and backstay settings. I'm just now calibrating track settings so the correct amount of check stay required for each increment of backstay can be applied without looking up the mast. I'm doing this by marking the track with numbers that correspond to numbers attached to a piece of sail batten that is strapped to the hydraulic backstay cylinder. As I induce backstay tension, the cylinder shaft travels along the numbers giving me an easy visual reference point, which I can then yell forward to whomever is handling the checkstays and they can simply pull the car back (using the 4:1 purchase) until it's at the correct corresponding number. The ratio of checkstay to backstay doesn't vary by windspeed (based on my own observations and those of my sailmaker), so this should work.
Any comments from other owners?

My Ballenger mast came with upper and lower attachment slots set up for Tball fittings. These were obviously provided for running backs. However, the boat was set up with wire checkstays that attach to the lower set only and run to the cabin top where they attach to Harken cars running on track. As you pull the car back (4:1 purchase) on the track the check stay engages. The lines are lead to Harken cam cleats. Management of the checkstays is handled by whoever is closest on the rail during tacks. This arrangement keeps the checkstays pulling on the mast closest to the appropriate angle (centerline), but the short run of track means the angle of declination of the stay isn't ideal - it pulls down as much as it pulls back - but it seems to do the trick. It brings the lower portion of the mast back into column in response to backstay pressure and it substantially reduces mast pumping in a steep chop.
I talked with my sailmaker (North) about whether to consider changing to running backs to improve the angle of attack and mast control when I get a new mainsail, but he wasn't enthusiastic. Basically, he said he could cut the main to respond to either method and any difference in performance would be negligible and not worth the bother and expense.
I'm interested in feedback from anyone who has switched over.

opinions
Of folks who have added in running backstays or checkstays to the mast- what are the methods people have found worked well?
Have you done it yourself or had a yard do it?
Did you put any kind of reinforcement inside of the mast?
Here are a couple of ways I have heard of so far:
thanks for any ideas!
