I'm confused at what you're doing.  In the blade level checker I described (and similar one-piece blade level checkers), the "level" is with respect to a virtual horizon perpendicular to the sides of the blade, independent of how the blade is mounted to the boot.

You have a Matrix blade, correct?  If so, you won't be able to use standard two-piece blade level checkers (with a separate reference horizon): Paramount sells a special one.  As an alternative, you'll need to get hold of someone with a machinist's square and adept with it's use.  The HDI gauge won't work on Matrix either.

Tstop, I’ve heard good things about Derby.  I’ve already ordered more Jerry’s, but I have some Derby’s on hand too.  I just don’t want the rainbow colours of them for this pair and was glad to find I had one more set that I could colour match.   My rainbows can go on the old white skates more nicely when I’m ready to switch to quirky. 

That's great about the boots!

Perhaps any figure skate laces of the right size might work. Unless Harlicks require thin laces. (Hockey laces are too wide for my boots.)

Also, do any of the pro shops near you, or other shoe or boot stores, sell "lace pullers". Basically just a hook. (So other hook tools might do.) Makes it very easy to pull laces tight. I used them for a while, before I discovered that round nylon utility cord of the right width is very easy on the fingers, and lasts almost forever. Though I recently replaced mine, because when nylon cord stretches after a few years or so, it becomes stiffer and harder to handle. A bit of a nuisance, because I had to melt the ends so I could push them through the holes - this time I used an electric burner, because I couldn't be bothered to buy matches.
