I got the SC-15 canopy for my -14 and in 2017 it cost about 300 more. It is worth every penny. I fly in the southernly sun all the time and never get a sunburn and it cuts down on the heat transfer considerably although I have to admit I can't compare directly to the normal canopy. But I'll be getting the SC-15 for my 8 if it is available.
