Spectra Vs. HMA

I'm buying a new canopy from Aerodyne, and was wondering if anyone could shed some light on what the differences are between spectra and HMA lines.

Thanks.

Please do a search, this topic is all over the place on this forum. In short, HMA is much more resistant to going out of trim than Spectra and can come in much smaller line diameter to decrease parasitic drag from the lines. HMA will not last as many jumps however, and the user MUST be diligent about regularly replacing the lineset because wear is not as easy to spot on HMA.

I have yet to find a single thread that compares the two side-by-side.

From what I understand, there are some safety concerns with HMA lines in that they don't show wear as well as spectra. A problem with this is that you may find yourself breaking a line unexpectedly.

These all have lots of information on both types.
