Well...
In years past, Sharkskinz were THE best, in my opinion. Honestly, the would stay together where others were just piles of parmesan cheese and rubble.
I used Armour Bodies then in 2003, and promptly tried to destroy them immediately. They did very well, but I was hoping for a little better.
I believe that Armour Bodies has improved their product from that time. I think, and I don't know this for a fact, that Sharkskinz might have had to reduce their overhead by reducing their use of some of more of their high tech, more expensive materials in a market that now has players from China offering full fairing product for under $300. I don't think they were as good as the fairings from the perspective of surviving massive destruction like they used to, but they are still many times better than what is available and consistent from some of the lesser names.
For me, since Woodcraft was now the distributor of Armour Bodies, I went that route. Jan, Eric, and everyone there has been great to deal with. I still think the Sharkskinz stuff is great and Armour Bodies is right up there with them now. Additionally, if one is budget limited, Armour Bodies has a second line. Can offer one the opportunity to save up and have two sets ready to go, so that pieces can be swapped while maintaining your signature look along with good fitment between pieces. Fitment issues are usually common with the very inexpensive bodies. Shouldn't see that with either Sharkskinz or Armour Bodies.
