No problem. I was the same way with the Axis when I first start shooting them....and they still shoot pretty well but not at the same level as when I first started.

Though the Excels are inexpensive maybe the difference in the construction process is making the difference. I am still not experiencing problems with them. In fact, I am shooting my best ever.....I am not necessarily going to give the arrow all the credit for that but if the arrow was of poor construction or durability then I would expect it to affect my accuracy level.

I guess only time will tell.
