You won...! -the right to make the board wider, and maybe implement dual mosfets at each end?

You may not believe me, but I was already thinking along those lines - the only problem is that I need to write more stuff on the boards, so that people don't get confused.

So unless I trace myself into a corner I'll add extra fets.

Myself , I think the original circuit is fine. Having the FETs on the end is fine but not absolutely neccessary. You could go overboard trying to include everything. Remember KISS.

Well I didn't take the "end" part to literally - I thought I could increase the board size by just adding a new set of mostfets. You could then use them or ignore them.

Ok, this is not the final design, but here is what I had in mind.

The board is 180x50 mm

nice, I will take that and a BA front end please.....

If possible, moove the thermistor between the mosfets, so you easily can choose, if only using one pair.

Or one could add a second set of holes, but I think in operation only one is needed per rail.

With two pairs of outputs some of the simplicity is lost and you'll need a lot more heatsink too.
