Well the 737 shouts minimums when you're there, perhaps that's where he's getting it.

What is this nonsense though about 'decide'??? As you fly the approach you call if you have runway, lights or some sort in sight as and when you see them. If the flight deck is silent all the way down the approach until someone or the aircraft calls minimums the decision is already made! Go around! Using a word like Decide could potentially give the wrong impression that you can now think about whether to land or not.

Not maybe so. If the PM calls decide and the PF can see to land he will "decide" to land. If the PF does not have visual reference the the PM will go around.
This can often happen when the monitered approach system is being used.
A few times this has happened to me and the PM has commented after landing that he has not seen a thing.
That is one of the advantages of a monitered approach.

The airplane does all the talking, so the PM just sits there and monitor all the stuff going on. If already visual at the "500" call the PF can decide to "Land" and calls it, if not he does at the "Miminums" call. Either "Land" or "Go-Around". A landing clearance is not required for a land call, that can happen later and quite often does. However no landing clearance by 50ft is a go-around.

And also some people set the DH on the rad alt when they are doing a CAT I approach which is also up for a much heated debate.

Hmmm, at the airline I worked for in the UK you could only use the DH for a CAT I approach if it had been surveyed and the CAT I DH was published on the landing performance paperwork.

What happens if you use the CAT I DH straight off the AERAD or JEPPs and there happens to be a big hole in the ground or a hill, it means you are going to end up to high or to low which could be the difference between missing out (if too high) or crashing (if too low)

Parking Brake Set ... and stuff like that

I don't think it matters much as the next chief/fleet pilot will change it anyway but if you've got an EICAS/ECAM etc then you could align the call with the screen message.
