W-Catter,
I only questioned these " close out " priced arrows in regards to their possible use as low cost small game and varmint arrows
I also am familiar with Black Eagles. However, not with the spinal tap verion, but do hunt with Z-slayers and have a few executioners on hand as well , and agree they are high quality shafts which do provide exceptional accuracy and durability.

But at a much higher cost than what I spent on the CE's.
I did find the CE Speed Freaks to be very stiff with what I precieve a thicker wall thickness, when compared to some other's I'm familar with. I believe I was told they retail at Wallyworld in excess of $7.00 each, and felt very lucky to get them at only $1.50 each.

When simply doing a spin test I can decern no visibly wabble nor irregularity.
When cut to 17" with the simple supplied plastic U shape nock and 125gn blunt or similar small game point such as a Judo of the same weight, they come in at or very near, 408 grains.. Just about perfect IMO, and for me they are very accurate and extremey stiff spine wise... ( as in I can not get them to bend in my hands at all ).
They have proven to me to be very accurate out to 40 yards with 125 gn field points

( as far as I have shot them to date .) Hopefully, they will be very usable as small game and varmint arrows which was my goal when buying them...
I cringe at the thought of launching one of my Black Eagles ( as I'm cheap that way )

at a small animal or possibly a small varmint which I would not choose to put in a cooking pot or skillet, when I feel even a good solid hit, which I know is right on the money,

is most likely going to result in a lost arrow

, thus the search for cheap innexpensive alternatives. :
Would I buy more of these "Cheap" $ 1.50 arrows should I find them ? Yes, especially if they were the Speed Freaks.
