Surprising that the Straggler works for you but not the Lauf. You didn’t mention sizes, but comparing (for example) the 58cm Straggler and the Size L Lauf shows similar stack/reach/ett:

I guess it’s possible that your sizes don’t match as close, but if they do, I’d take a hard look at other fit details like stem height/length, handlebars, etc. Its amazing how little it takes to make numb hands…slight adjustments can put more pressure in the wrong spot on your palms and make a huge difference. I had some numbness with my current bike that mostly went away with different handlebars…but I then put those old bars on a different bike where they don’t seem to be a problem.
