Glad it worked for you.
As I noted in my earlier post, different physical weight arrows will behave a bit different dynamically even if they have the same static spine.
If you go to a considerably physically lighter cedar shaft, say 50 grains or more lighter, it will act dynamically stiffer and may impact a bit to the left vis-a-vis your heavier Doug firs.
Of course, unless you have a spine tester, you won't know for sure if your cedars and Doug firs are the same static spine, so will be difficult to pinpoint the cause of different arrow impact if you do experience it. Let us know what you find out.
