Like I said....I have no idea if the difference in tip weight would affect your spine.....but either way...you're telling me you're getting NO fishtailing. So....going on your word....I'm assuming your arrow has got plenty of ass to handle the spine issues.

No. 1 - I can't fathom the difference in anything other than a vertical plane difference switching from lighter to heavier tip weights (if everything you're telling me about arrow flight is correct).

No. 2 - I can't fathom going into the woods with the "band-aid" you just put on a gaping wound.

You asked....we told you.

Good luck.
