Phil, what do you want to know about them? E-mail me with any questions. I have been shooting them for 2 years now and love them. Like I said, I like these Epsilons, but when they are gone, I am going right back to the nitros.

The nitros are not really rated for spine. The yellow ones(the lites) are good up to about 55 or 60 lbs I think. The web site will tell you for sure. The other ones(orange, green, and gold) are good up to 90 or 100 lbs. The different colors indicate the weight per inch of the shafts. If you go to a dealer and he has a chart that tells you what shaft to get for your length and draw weight. It has less to do with spine and more to do with getting you a combo that will put you close to 6 grains per lb of draw weight.

Also Jackson's weight calculator is about 10 grns off I think on the nitros. Mine are always a bit heavier than his calculator. The SME Epsilons are the same way. I know why the sme's are off. He has the inserts at the wrong weight. They are actually 24 grns I think. I also get a completely different FOC on the nitros than the chart. It is always more when I actually measure it. But it really doesn't matter as long as they fly well, and they do.

My nitros cost about 50 bucks for six finnished with feathers. A little less with vanes obviously.
