When the application structurally requires primarily 0/90 fiber orientation (e.g. boats, hockey sticks), TeXtreme is a better option because it offers higher strength-to-weight ratio.
When the application structurally requires primarily single-direction fiber orientation (e.g. bikes), then TeXtreme effectiveness is less and is largely relegated to improving impact resistance and aesthetics?
Oxeon makes TeXtreme in a variety of configurations. You can get their spread tow reinforcements in 0/90 and +45/-45, unidirectional tapes, and hybrids.

But it seems like their really distinctive product, the thing where they make the most significant contribution to the array of choices isn't uni, a lot of companies do that... it's the that spread woven.
Hybrids are really interesting for projects where you need woven, and you can get some pretty nifty custom weaves done with it... if you are buying enough, it is possible to get some crazy variations. And not just in material types but also the proportion of the fiber woven in each direction, which can improve on the engineering compromises of using woven in some applications.
A simple example is e-glass cloth for surfboards, with almost 70 percent of the fibers run longitudinally and 30-some percent run in the direction you need less strength, from one side of the board to the other.
I have used that as sheathing for ultralight, thin wood strip boats. The wood fibers provide significant stiffness fore to aft, so you run the surfboard cloth with the strong direction against the grain of the wood.
