Do I interpret correctly that when you say "the green compound" you're referring to Swissstop GHP II? (I'm not familiar with Magura's lineup)
If so, I'm extremely curious to hear your opinion of how the two pads compare, both in the dry and in cold & wet conditions.
The inverse is my case.. never had any Swiss Stop pads in my hands .. to have an A/B observation
Magura
HS33 R*| MAGURA
their color/compound range is (quote) Black: stock pad, general purpose ..
Salmon (by popular demand, made for the German brakes, in Oregon) Wet , rim friendly,
they call it their competition pad for polished rims
Grey for hard anodized and ceramic impregnated braking tracks ,
And the Green; the competition pad for the same CD & ceramic face rims.
Just inferring based on appearances .. [FYI 0:54 in of 1:28 video of accessories. ]
Once I scoured thru the CD coating on the brake track, the green pad was popped off
and the stock pad popped on, after wearing that pad set down with my daily transportation
the next set bought was the Salmon color compound..
as a Porsche fan you may like the HS33 better than the V brakes ..
(except for the money put out as NY theft candy).
