Perhaps Adox will market this product better than Paterson.
You may also find the Spur range of developers of interest as well. These like the Paterson developers appear to be somewhat more specialized than the regular general use fine-grain developers like D-76/ID-11.
Have a look at Bruce Robbins site where he often uses D-76 1+1 to compare results.

Is Acurol-N a clone of Rodinal or a variant of that type of formula? At those dilutions I am curious: The results seem to be somewhat like Rodinal. It is not clear whether the speed was determined. D-76 1:1 is a compromise between solvent fine-grain developers and acutance types. It is very forgiving too, and probably is ideal for Tri-X Pan for general-purpose use, especially in uncontrolled light (such as in "street" photography, where exposures are seldom "on the button"; putting the camera on a tripod and shooting slow films will not tell you much about developers that are best-suited for such applications).
Using slower films such as Ilford Pan-F Plus, Delta 100, Kodak T-Max 100 or Fuji Acros 100, D-76 1:1 may be still produce a little too much solvent effect. In such cases, D-76 1:2 might prove worth trying. Developers need to be evaluated based on the type of photography one does above all, which is why I advocate D76 1:1 for most people: you will find it produces a negative that has a nice balance of properties (speed, graininess, sharpness, compensation), and is not that critical in use. The advantages of a developer such as FX-39 or Acutol can be seen, but only if your technique and your lenses (including your enlarger lenses) are first-rate. I have a Leitz 50mm f/4.5 Focotar-2, which is the finest enlarging lens ever made in that focal length. The contrast and sharpness are superb.
For slow films I found the old Tetenal Neofin Red and Neofin Blue developers preferable to Rodinal, which I regard as a vastly over-rated and quite inferior product. I used to shoot some Adox KB-14, but quickly grew tired of the slow speed and limited latitude. I ended up standardizing on Tri-X and FP4, which could be developed together in Ethol UFG developer (3.5 minutes). When I needed something a bit more refined, I used FP4 in Acutol. I gave up using the slow or exotic films and developers since they were of limited usefulness. I could make 11x14 prints from Tri-X developed in UFG with very little grain, and from FP4 in UFG it was all but invisible unless you stuck your nose on the print. Adox KB-14 (ASA 20) was simply impractical, and KB17 (ASA 40) was not any better than FP4 in the grain department.
Overall, FP4 in Acutol was exceptionally good when I didn't need the speed of Tri-X. I abandoned Adox KB14 and Neofin developers and ended up with just two films (Tri-X and FP4) and two developers (UFG and Acutol). So, Neofin, KB14, Rodinal, FRX22 and all that sort of thing...just proved a waste of time. There were numerous high-acutance developers on the market for a while (Ethol TEC, FR-X22, Neofin Blue) but all of them were inferior to Acutol.
FP4 Plus is a better film than FP4, and much better than FP3. Tri-X was much better than HP4, which was discontinued around 1975 I think, and replaced by HP5, which was replaced by HP5 Plus around 1989. Tri-X and HP5 Plus are quite comparable and interchangeable.
Since I worked in a camera shop I could order and try out all kinds of exotic products. Most were either too much trouble or inferior to products that were easier to obtain, except FP4 and Acutol. I used just about every kind of paper and film out there in the late 1960s and early 1970s. Remember Agfachrome?
UFG is vastly under-rated:
