Hi nej,
This thread may be a record for the fastest moving thread with the largest number of posts in a single day. It took some reading to catch up to it 
All the components are good quality but I have no idea how they would feel combined together for you. You can read a little more about shredded latex toppers post #38 here and wool toppers in post #3 here but these are the types of more complex and unusual combinations that only your own experience can really know how the combination would feel for you. I would tend put the wool above the latex though so it’s on the top surface of the mattress and you can take advantage of it’s temperature regulating properties although this will also affect the ability of the shredded latex to “flow” around your pressure points. One good feature of the flobeds shredded latex topper is that you can adjust the fill of the latex in each section to customize it based on your actual experience.
This is by far the best approach for a DIY project IMO so you enjoy the process regardless of the outcome of any particular layer or component choice, are comfortable with any trial and error that may be involved, and aren’t overly disappointed with any “mistakes” you may make along the way.
You may have done this already but when you do a forum search on your city make sure you have changed the “find posts from” setting to “any date” because the default is a year and many of the forum lists were originally written more than a year ago even if they’ve been updated or edited since then. It may also help to put in the name of nearby cities or the nearest larger city because some of the lists have been researched to about a 100 mile radius.
I would keep in mind that natural rubber has a higher density than synthetic rubber so a blended Dunlop will have a lower density than a 100% natural Dunlop in the same ILD.
A phone call will bring much faster results with most smaller manufacturers and email isn’t particularly effective for questions that have more than a single sentence answer, any “it depends” in the answer, or needs a more “nuanced” answer.
Besides the method nej mentioned … you can copy and past the words you want to quote from another post and then highlight them with your mouse and click the quote icon (the wrd bubble) in the top row above the emoticons it will show up as a quote.
An electric knife with a straight edge of some kind as a guide works great. You can see some pictures of some more complex cuts here with the latex squeezed in between two boards.
I think you got “caught” in one of the forum settings I use to help guard against spammers who post many posts in a very short period of time. It’s set for 1 minute in between posts as a minimum
