I ALWAYS listen to the manufacturer in cases like this but on this occasion I dont trust the advice I got. It goes against what I know and what (it appears) industry experts build to. Thats why I asked the question, not to cast doubt on your wheels but to get a number from an experienced source.

Originally I built to 90kgf, why? Because front wheels are more lightly loaded than rear for a start and they have better bracing angle from the spokes. Also if you buy DT swiss's flagship 180 hub with ceramic bearings and all the bells and whistles it tells you not to build radial and if you do keep the tension below 100kgf. So 90 seemed reasonable, especially as my hub was previously laced 2x and has some spoke hole marks and scratches from that.

The wheel rolls fine with either tension but im thinking now of putting it back to 90kgf so there is some extra "headroom" on the tension. I suspect it would loosen up if it wasnt for the spoke freeze. In my mind 115 seems high, given that the front wheel takes a lot less load than the rear.

Hmmm, need to think some more.
Don't forget that inflated tires unload the spokes some. If you keep your tires well inflated there is an automatic safety factor built in.

I am just puzzled that the priciest hubs have the worst limitations on build design and tension. There is something wrong there. Radial is nowadays standard, and the best hubs can't take it at normal tensions? That's not right.
