Not sure if you really meant what you stated here deerhunter. The fletching does not push the arrow through the air. All fletching provides drag and helps to stabilize the arrow. The harder the helical the faster the arrow rotates in flight. The tab on the quik fletch vanes caused the arrow to spin much faster resulting in quicker stabilization.
If your bow is properly tuned very little fletching is necessary. But shooting in windy conditions or shooting large fixed blade broadheads and at longer distances, you should have a combination of a good spined arrow, adequate fletching and a %FOC of about 10%.

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?

BINGO! you hit the nail on the head, if bare shaft arrows are not flying right ; vanes and broad heads, will only magnify the problem.

When in doubt, go back to square one, start with bare shaft.
