Which Stem Installed?

I just noticed that Wunderlich has a 90 degree "for spoke rims, not cast." Is that because a cast rim stem won't seal in a spoke rim? (FYI I have spokes).

Basically my question is, did I get the wrong valve stem? If this is something that can cause a long term leak I'll get it replaced. Otherwise I'll wait 'till I need another new tire.
If you are going to ride your bike on road and not in loose stuff off road the angled stem seems to make sense..but just for me a 90 degree stem doesn't work for my off road is too vulnerable to getting ripped since it is oriented 90 degrees to direction of rotation...I try to reduce all "what ifs" that could cause a component failure....can't ever make it bullet proof but often a little thought can give you an edge..

Putting air in or gauging pressure is more about technique that angle of stem...just my thoughts.

Did you soap test the stem to see if it is leaking? Most often it is the stem valve and not the stem..
