Dyneema is GSP and is the trademark name owned by the Dutch company that invented GSP. All GSP is made under license from this Dutch firm.
If you decide to use GSP, you might benefit from Geoff Wilson's knot book on "superbraid" as the Aussies and others call gel spun polyethylene. For example a bimini twist requires 40 initial turns [memory?] vs. 20 with Dacron. The arbor knot Wilson recommends for GSP is not what you see in non-GSP specific knot books.
