I have tried out two Lat. 64° Fuse . One in Gold-line(175g) and one in Opto-line(176g). They both fly very good with minimal fade through out the flight path but the one in opto-line holds the line in a more stable way, meaning that it don´t turn over as much as the one in gold-line when you throw them with to much power.
This is by far the best midrange I have ever used.
