I've had 4, three Streamers and a Fortress. For me, the 91 Streamer was the most complete and beautiful bass I've owned. Sadly, the truss rod nut thread got stripped on my 87 and my luthier discovered it was made of aluminium (seriously) - it's a suprise it lasted as long as it did. He also showed me another broken truss rod from a Corvette when I collected it, the truss rod was only around 3 mm diameter. The truss rod replacement cost me nearly £300 and left a sour taste in my mouth.
With that niggling doubt in the back of my mind, I sold them all.
