That would be my concern, the weight. Of course it is going to put more strain on the actuators.
If everything is clean and the inserts turn smoothly then there is nothing wrong with the stock setup. I don't see a performance advantage for stock application, meaning using the secondary actuators. For all out performance I would use them.
My experience is to stay on top of your oil changes, make sure the thing gets to full operating temp all the time use good fuel, and get into it so that you use the secondaries at least occasionally. Main reason they carbon up is from non-use. People 'taking it easy' and 'babying it'. Usually seen on those where the new rotary owner was use to a recip that they never took over 4k for fear of hurting it. Have to tell them, drive it take it to red line once and awhile rotaries are meant to rev.
Doing a Redline SI-1 treatment once a year helps also.
