RE: Some Streamlined related....
Just a note of caution. I was very interested in the Streamline Redline skinny mast base extension incorporating the Euro-pin receptacle, but I was trying to match a Chinook SS universal assembly as part of the plan. Unfortunately, no deal. Chinook's Euro-pin doesn't work in the Streamline base, since proper retention cannot be achieved between the two components. However, if one was to stick with the Streamline universal matched with the Streamline mast extension, everything is sweet. Streamline uses the North pin component (the standard), so the problem is truly with the configuration of the Chinook pin. Yet, the Chinook to Chinook combination works with no problem.
