I'm not adamant about the 90degree or 45degree welded but...
1) I prefer not to fix a skills issue by changing equipment
2) When the stage/deco bottle is full the dring swings forward, when its empty is swings back, the 45degree welded dring would be a bit messy to have multiple stages on, a leashed stage or stages would be especially tangled and cross clipped. 90deg welded would be better than the 45deg but still not really ideal.
Basically now is the time to learn to work with the "normal" dring that will flip back and forth. Beginning with the end in mind and all that jazz. Using the correct clips with a large eye and medium hook size, putting your first finger through the eye, the thumb on the slider and using your middle finger to flip the Dring into clipping position is a learned skill.
