Note that the DT350 option would let you sell the DT370 to recoup some costs too. (I'd check spoke calculator or hub flange dimensions first to make 100% sure you're not going to need new spokes).
So it's more work, but actually the DT350 option seems best.
Where is the DT350 micro spline hub 176 euro? That's really cheap, and I need another one before the summer.
