Help me decide - Big or small bolt pattern?

Functionally, there's nothing wrong with staying with the small bolt pattern, and the factory small bolt pattern Kelsey/Hayes disc brakes are arguably better than the later large bolt pattern disc setup. But as previously stated, wheel availability comes into play; as does parts availability- which is already kind of dicey here in the U.S., I can only imagine how it is in Sweden.

And not only in Sweden. Outside of North America in general.
My Demon has originally (K/H?) disk brake rotors, but small bolt pattern hubs.
As I've been lucky enough to find a BBP road wheels (mag500) set and later, a BBP rallye wheels set (both 14" diameter), I had to take a decision.
I opted for 1" BBP conversion wheel spacers.

Works very well, slightly widens the wheels and fills better the wheel arch.
No caliper or drum clearence issue.
And this way, it's still possible to mount SBP wheels if needed.
