Now that Ive had some sleep and can think clearly again....
There are obviously many different approaches, all valid ones. The OP had seemed to have made up his mind to purchase gear and asked which of the 2 sets he had chosen would be best for him. Obviously that is a hugely subjective question, my intention was purely to look over his choices and see if any issues jumped out at me.
Based on my PERSONAL experience and that of my diving community, I made some comments and suggestions based on what I would do given his situation. I also had a look at some options that would achieve the same result at possibly a lower price point since he seemed to be on a pretty tight budget.
As far as the DIN issue goes, as I said i haven't dived anywhere where it was an issue, now I know that it is an issue in some parts of the world I will investigate a bit more. A DIN/yoke adapter is not ideal but would allow some choices. What I have also found is that all the regs I have used / bought have been rated to 300 bar, but the yokes have been limited to 232. When I ordered the DIN version of my regs, I received a 300 bar DIN. granted, HP fills are also not super common but I have found them and it has allowed me to dive longer with smaller tanks on the occasions that they have been available, an option i would not have had with a yoke.
Again, the usual disclaimer that YMMV and that these are PERSONAL opinions was implied but not stated definitively by me, Im going to blame tiredness and move on.
BTW, thanks for the info Murky and the way you gave it, Ive learnt something new while trying to help someone else, which is kinda the point of boards like this in my opinion.
