Favorite paint system discontinued!

I have just been told my local trade shed is discontinuing the paints I have been using for around 7 years! it is Sandtext exterior gloss and primer/undercoat, I really like it as it is long lasting, is a three coat system, and is white spirit based.
So am looking for a good alternative, I don't want to use Dulux weathershield because it is a 4 coat system. And I want a three coat , I looked at Sadolin supadec opaque today, looks interesting but am not sure about the water based aspect for three reasons.

1. I recycle my white spirit so I never have to throw any down a drain where as what am I going to do with water?
2. I am dubious of using water based in our climate.
3. I do a lot of epoxy repairs so not sure how it would go on that.

I looked at Johnstons again interesting, but they say 6 year life span Ideally I want 10 years.
Any thoughts folks?

 

Even the Dulux one coat requires 4 coats according to their data! I generally use gloss as that's what most customers want. I repair sash windows and then repaint, I do a high class job so dont want to let my customers down by not sticking to the required number of coats, I don't see how I am over complicating , I just want an exterior paint system that is reliable.

 

Update, Trying out Sikkens Rubbol XD again, did use it a long time ago but in October when v. cold and it orange peeled, seems to be going on quite nicely in this hot weather, pretty good coverage.
