I have built with both POC and Alaskan yellow cedar. The tops I had were in the heavier end of what WRC would be, at least in my experiences. All were relatively stiff and were thinned down to the .110-.115 range for my build style. The POC definitely has a much mellower (less pungent) aroma, most noticeable when sanded or cut. The Alaskan, on the other hand, is aromatic for a long time. The photo shows an Alaskan topped guitar built in 2003 that still smells like a cedar chest today...good for keeping moths out of your guitar case
...and is really a pleasant smell IMHO.If you stick your nose right into the soundhole of the POC guitar (delivered at this past Healdsburg Festival) you can barely get any aroma...it's there, but VERY faint.
If you haven't tried the Alaskan cedar, that might be a future build for you to try. The photo is on a koa body and it is a spectacular guitar. Lives with my good friend, Steve Hawkins, in Portland OR. these days
