Mark's decals are purely the best for HC mags, the only suggestion i would do to you if you plan to use your mags for more than display is to glue the letters with the loctite's hybrid glue.

It will resist to water, hits, it's flexible, and the most important it is transparent and nearly gives you 3 minutes to move the letters a bit, but the bad side of this glue is that you have to keep in place what you stick for 5 minutes.
If you prefer a faster glue then i suggest you the professional glue from loctite, but only use it with gloves.
My suggest is to first put the letters on the heel cup at the place and the way you want it to be with the original glue.
I used this picture to try to make it like the originals mags but and the best advice is to use the couture that's upper the heel cup as center of the letter positioning

Then take out one by one the letters, peal out the glue of the letter with your finger and then put the loctite glue.
I personally used a strap on the heel cup to make the letters be perfectly straight.
For the swoosh you'll find out by yourself that the cut Mark did is perfect and will make it easyly to put in place, but i very higly suggest you to put loctite's hybrid glue too, put first a very thin layer after removing orignal glue, the easyest way to apply to loctite's glue on the swoosh is to wear a glove and apply the glue all over the swoosh with it, then try to walk a bit after and see where you need to put a bit more, just don't put too much and take your time to do it, so after your swoosh won't move anymore whatever you're doing.
Hope this helped you, if you have any further question do not hesitate to pm me.
If you could post some pictures of the new HC mags version with more flat laces i would be very curious to see it, and if the toe box is still horrible as i used to be i highly suggest you to watch cavx iron steam toe box mod, it's the easyest, safest and best way to modify it.
