Well, i dont own one, yet, but i did get to examine a few recently at a local shop, one of each, a Tanto and SP in each size. First, i will say that if you do buy one, make sure you get a "good" one, by that i mean that of the 4 i examined, only one had good lockup and no blade play. I fully admit that if you get a good one, like that one i mentioned, it looks like its an extremely strong and capable knife, but, the other 3 had various flaws, for example, both of the smaller version had a liner that went WAY too far to the right, well past the center of the blade, that is a defect. Also, each had some blade play. The other large Tanto also had these problems.
So, to conclude, i think that if you get a good one, it will be a great knife, you just have to make sure you do get a good one. Here is a hint. If you order it online, tell the dealer to please make sure the knife he sends you has good lockup and no play. Be nice.
On a side note, after i saw them, despite the flaws i mentioned, i must admit, i was impressed with the build quality of the knives, they really seem extremely robust and very strong, and the large models are pretty big folders. Then, about 2 weeks later, i got to see a real Strider GB, i couldnt believe it, it made those robust, large Buck/Striders seem like flimsy little toys in comparison! The AR/GB striders are gigantic and built like no other folding knife i have seen. You really have to hold one to appreciate it, its almost comical how big and strong it is.
