Everyone says RE8s are softer over the axle than a 7. Based on having both in hand, I would say its true, because the RE8 is physically softer. So that may be an option for you.
The other reason why the RE8 will ride softer is that it has more air volume. So in theory, and expansion tank would create a place to store more air volume, and it may create a softer ride, but I am not positive.
I made the notches on the Datsun mini air tanks in case I thought it was necessary to run expansion tanks. But with sleeve bags I don't think it will be necessary.
