Where were your bareshafts hitting compared to your feathers? Compared to your vanes?
As others have mentioned, I start over from scratch whenever I mane a change like that. But I also don't like to have my fletched arrows not shoot to the same poi as my bareshafts. If any difference, only elevation.
Not worth a conversation to talk about clearance issues. Powder test and you'll have your answer, no reason to speculate. Have you paper tuned with the new vanes in place?
