Technical carbon arrow Question

Okay, my buddy and I were shooting last night, and he noticed that my arrows were flying funny when I was shooting.

First I'll describe my set-up and then I'll explain my thoughts, then maybe some of you may have suggestions on what the problem may be.

I'm shooting a Hoyt MagnaTec: 65lb draw weight with a 31" draw length.  The arrows are Gold Tip XT 5575 arrows (27") with 100 gr. tips.  3 - 4" vane fletchings  The total weight of my arrows are around 369 gr. including all components.  The bow shoots approx. 269 to 275 fps.  When I went on the following site to calculate what minimum weight arrow I should be shooting, it looked as if I may need more weight, but I don't know for sure.  I also was not sure what they meant by "ENERGY" cam vs. "SPEED" cam?  My bow is a single cam bow...Hoyt's Versa Cam.  I plugged the mumbers in for Energy cam.  heres the link... http://www.huntersfriend.com/arrowhelp/AMO-Minimum-Arrow-Weight-Chart.htm

What my arrow is doing:  The arrows group well and hit where I'm aiming, but the****end of the arrow seems to fling around some, causing the arrows to enter the target at an angle instead of straight in.  It gets worse as I increase my shooting distances.

My thoughts:  I'm thinking that the arrows need to be heavier or I need a stiffer spined arrow?  If I add weight, does it matter where I add the weight?  Front or rear or is front my only option?  Or should I try a heavier arrow all together.  I think heavier in the front may just make the back end fling even more.  I know I'll probably just end up going to the archery shop for assistance, but wanted to hear some feedback from you guys first. 

Thanks in Advance Guys!

    Years ago when i was shooting a bow i got tech bullitens from easton that may now be on line, that explained how to correct "fishtailing" The first thing you need to do is papertest a shot to see which way it is fishtailing. I'm sorry but i no longer have these bullitens but i believe that is your problem and hopefully you can find it on the web.

    I definately suggest taking your bow to a good shop.
     
    I would say your arrow rest needs adjusted, rather than changing your shaft. I have been told by more than one bowshop that the 5575 shaft is extremely versatile, meaning it is fine to shoot out of many different setups, fast and slow. They are what I shoot.
     
    Do you notice any fishtailing just as your arrow leaves the rest? Are any of your fletchings messed up from hitting the rest?

    Does every arrow do this?  Fishtailing the same direction?
     
    If your fletching does not hit your rest and you answered yes to the above, you nocking point and arrow rest are not balanced.

      Paper tune your bow. Shoot it through paper and read the tear it will tell you what to move. Maybe marty has an easton chart for tuning your bow. 
    You tune your bow to your arrows by moving your rest up and down for porpoising( up and down oscillation) or move your rest left or right for fishtailing (left or right oscillations... You also need to inspect your fletchs very closely to look for any deformity on the ends which would indicate a fletch clearance problem. I once shot 125 arrows paper tuning a new 3D rig. With a better tuned rig you will gain speed and accuracy..

    i agree with the above... the arrow rest and ur nocking point is important... take it too a good bow show they can show you... paper tuning will help  you fix the problem

    Thanks for the info and feedback guys...I guess I should have mentioned the type of rest I have is a NAP Drop away rest which should have no effect on the arrow, but the nock point may be the problem then.  Makes sense.  I'll head out to Shooter's later this week and get her paper checked and all checked out.  I'll let you guys know the results later.  Thanks for the help again!

    A fall away will not affect the arrow after the shot and it falls. But it must be set so the arrow starts out in the perfect position to start the arrow on its way.

    With fall away rests, you not only have to tune the center shot, but you also have to tune the timing of your rest. My trophy taker was not dropping fast enough with the bungee chord that was included. The fletchings were making contact with the launcher. I had to go to a non stretching chord to make sure the rest dropped in time.

    How do you like that rest? I'm thinking about going to a fall away. I'm having a slight tuning problem myself. Trying to get fletch clearance for these new blazer vanes.

    I like the trophy taker, but it seems there are a lot of good dropaway rests out there now. I can say that arrows do not fall off the launcher, and the rest is quiet so long as you put some moleskin on your riser where the launcher falls onto it.

    No tuning on the muzzy zero effect.  Really, it does have zero effect.

    bings,
     
    I like the NAP drop away.  This will be my 3rd season hunting with it, but I did want all of you to know that I noticed a skid mark on the bottom vane of all of my arrows that I completely overlooked before.  The mark is consistent on all the arrows and I think its making contact with the rest somewhere along the line.  This has to be the problem?  I'm going to take it to the shop this weekend to get it checked out and re-tuned.
