TJM wings bend on the bar under light impact and take out the corners easier on the D1, ARB is much stronger in this regard.
D1 ARB bars dont rotate. The ARB D2 bars had some issue with this which has now been rectifiied.
Personally I'd run the ARB and Safari Combo, safari has better flow characteristics, even when I had a 5.0L supercharged V8 sucking through it.
