I have been been using  a slicone tire dressing I get at Wally world.  Works very well.

ventilator,

Thanks for your opinion.  I'm happy you have found something that works for you.

That stated, all I can say is I have not experienced the issue/s you describe.  This probably due to having simialr experiences with 2 other brands of ready to shoot arrows.  From that point on, I went to rolling my own.  Bought GT Laser II shafts, was successful with them, and later was asked to join GT's staff.

I understand the topic was Laser II's, but as stated earlier Laser III's and Laser IV's were developed for the higher energy bows.  Sorry if mentioning a possible solution to those having a similar problem was upsetting.  In reply to the screw machine comment, I noticed some of the same concentricity issues as well 3 years ago, but have seen where that issue has been resolved.

Comparing your arrow of choice, which is a higher cost premium arrow vs a standard price point standard grade arrow, is apples an oranges.  Nuff said.

Have a great day.

ventilator,

The speeds you are talking about are not really meant for the Laser II's even though I shoot them over 380 without problem.  Gold Tip makes both Laser III and Laser 4 shafts with a stiffer spine for those speed bows.

Bow tune, ie. cam rotation/timing has a major affect on the arrow.   If one cam is off just a bit, the arrow will not get string pressure on center and will shoot erratically, correct spine or not.  Way too many variables to condemn just one part of the system.  JMHO

As Obama would say, Look, I'll say it again, check out my threads and posts on arrow tuning, do the search, it's worth it!

We have a multitude of people coming into the crossbow discipline now, and it appears most have little or no archery experience.  Arrows have SPINE, and one must find the proper location for that spine in order for arrows to group together! Plain and simple.

Just yesterday I set up a new vertical compound, and wanted to try some arrows I had built and tuned for a different bow.  Result?  They shot a low right tear through paper with the new bow.  Rotating the cock vane on those arrows gave the desired "Bullet Hole" tear we desire for a perfectly tuned bow.  WHY?  The arrow reacted differently out of the new bow due to SPINE.  It works EXACTLY the same with a crossbow.

All those saying buy 2 dozen to get one good dozen, in my opinion, are either not knowledgeable enough, or not willing to put the time into achieving the results they desire.

Yes, I'm Pro Staff for Gold Tip, but I'll tell you this.  The last dozen standard Laser II's I set up, only one didn't shoot the same, it was 1" out at 20 yds.  The others would all cut the same ragged hole.  With Lazer II Pros, I have even less issue, so much so that I don't even weigh them anymore, just assemble insert and nock, shoot bare shaft to find spine, fletch and I'm good to go.

I'm sorry if I offend some here, but this my experience.

You need to "tune" the spine of Each arrow to YOUR bow.

Do a search on my threads about arrow tuning.  It works.  The short version?  The arrows that don't hit where you want, rotate the cock vane to a different position.  Easy with flat nocks, requires rotating a moon nock.  Start at close distance you feel comfortable with, 10-20 yds.  You might be surprised.
