Heat range of the new OS RP plugs
Does anyone know how the new RP plugs compare to the old P plugs? I am looking for something that compares to a P7 (medium) plug. I thought I could just get a RP7 since I assumed the heat ranges between old and new plugs were comparable but I noticed that OS now says RP6 is medium (P6 was a hot plug).
Did OS just change their 'heat scale' (how hot they think a X plug is) around, or are the plugs actually different? Because, even though that RP6 is now called a medium plug, if its heat range is anywhere close to that of a P6 I don't want it. Way too hot for my liking.

I am not familiar with the new plugs but the number generally refers to the wire size of the coil. Typically 5 hot, 6 medium, 7 cold, 8 very cold. Some refer to them differently, like 5 very hot, 6 hot, etc. but the coil (and thus the heat range) is about the same.
