I am certainly an advocate, but JCM are mostly intended for bare skin. If the area is covered by clothing, the morphs should be turned off. DAZ did not include INJ/REM poses for the JCM on V3, but they are easy to do. I have not done the individuals, but I have poses that remove and inject the lot of them. An alternate method is to hack a pose file that sets the rate to zero - and have another to reset the rate to default. It is just 5 lines of code, it can be altered to make the morphs FBM or PBM - two minutes work.
