I have the Johnson Backstay adjuster and has worked great past 4 years.
Haveing a Headstay johnson lever is better but as I just stated thru bolts will weaken mast,

I just don't see this as working as the backstay on our boats that have one is there more to tune the rig by inducing bend in the top of the mast or helping to support it going downwind. The back stay is usually never tensioned as much as the forestay. So if you tried to tension the forestay with the backstay you would have way more tension and bend in the mast than what you want.
As far as drilling holes in the mast. A couple more holes a few inches up the mast in order to move the hounds is not going to weaken the mast to any noticeable degree. If you go more than a couple inches like we did then I think it is prudent to move the shrouds up also (maybe a good time to finally replace them).
In our case moving the forestay up the mast some allowed us to still use the original forestay inside of it if we want. The....
... original hounds are where the top arrow is above with the new ones and the furler above that point. The original forestay can be...
...pinned to the bracket above on the bow roller assembly.
You would not want to use this option as an extra safety option to keep the mast from falling as it would be a pain to get the head sail to come across. I have it so that if we wanted we could still use our original hank-on jib if we wanted to or possibly a smaller storm sail which we don't own at this time. Also I'd like to try and run the Genoa off one side of the boat and our old jib of Genoa off the other side hanked onto the old forestay. Haven't done it yet but I've hear of cruisers running with the wind with two head sails (one on the wisker pole). They like it as you don't run the main, so worries of an accidental jibe go away,

Mac-Venture Links[/quote]Wrap around mast strap on 3rd pic., how do you raise main past it and what is the Jib halyard pully doing there?
I dont like the Idea of raiseing the Hound up 4-6 inches that require another tru bolt that weakens the mast.
I do like the idea that one only has to thru bolt 4-6 inches without sail cuts and shorting standing rigging.I have the Johnson lever on backstay
so I can pin the forestay.
It works just fine but if I was to Get a New Headstay I would shorten the Headstay by 6 inches, include the Johnson lever and Shorten headsail Luff by 6 inches.
Most pictures I see of the Johnson lever at the Headstay is all the way to last pin without any adjustments.
Keeping Headsail up higher by 8 inches greatly increases View forward.
Fact remains that the Johnson lever at Headstay is best for tight Standing rigging and Backstay Johnson lever is second best.
All depends on you installing it on headstay and if raiseing the Hound is worth the loss of strength /or shorten headstay and luff of sail.
