Plate insert patterns (UPM, Allflex)

You can see that the mounts screw into the 4x4 holes but the plate axles are pushed out towards the nose and tail.

It sounds like the Apex 4x4 mount system solved the problem that others weren't able...outboard  axles and mounting in the thick portion of the board.  Would you say this is the ideal mounting system then?

Utilisation of any 4x4 insert plate system then depends upon what the actual spacing is between the front and back insert sets and what the designed offset is from the centre of the effective edge. I own a snowboard where the max C to C stance distance using the 4x4 inserts is 48cm, and another where the distance is over 60cm. 

Any design is a series of tradeoffs and compromises. Long isolation plates with long interaxle distances give greater torsional resistance but need to have their inserts in a thinner part of the core.

Most plates have a restricted choice of interaxle distances determined by the holes that allow the plate to be screwed to the isolation mechanism. Bomber's 4x4 mechanism has considerable positioning flexibility to allow a working combination of the boards 4x4 insert packs and the BBPs interaxle distance options. But I still struggled to find good combinations on some of my boards. 

The advantage of a 12.9 cm X 3 cm pattern (Apex/UPM/????) or the AllFlex pattern is that the board designer has optimised the board's whole construction around a plate being used and fitting a plate is then generally very straightforward. 4x4 setups, in my experience, take much more fiddling to get the best performance.

Late to the party, summer whizzed by.  A few items:

Based on my conversations with Fin at the time, the motivations for calling it UPM were not nefarious.  Nobody is trying to get rich in this industry, so there is no point in cutthroat tactics.  Fin and Sean recognized that the Apex plate was the state of the art then, and wanted to make that insert pattern into an industry standard.  This was intended to be a good thing for Apex and everyone else because then stock boards could be made to that standard and people could try different plates on one board.  This made Apex's plate (and Bomber's and Donek's and Jasey Jay's and whoever else's) more accessible as people could get into the world of plates without having to buy a custom board for every plate.  I think keeping the ASIP name would have decreased the likelihood of the pattern becoming standardized, IMO.

This is all somewhat moot because Allflex/Iron Rock have basically conquered the racing market for now.  A shame, because the Apex is awesome for freecarving, and still good for racing, if not at the top levels.  Kessler is not even making stock UPM boards anymore.  Good thing you can get an Apex plate with Allflex hardware, or swap your X-Plate's UPM hardware for Allflex hardware.

The 4x4 version the Bomber Boiler Plate also properly moved the axles towards the tip and tail so that your feet were mostly inboard of them.
