Based on what you wrote, it seems that you don’t feel comfortable when a fully assembled racket (with rubbers) is too head-heavy. That would mean you need a blade that will feel lighter when combined with Butterfly Rozena rubbers.
In this case, it’s not only the total weight of the blade that matters, but also the balance between the handle and the head. So, you should look for a blade that meets two criteria: it should be as light as possible, and its balance point should be as close to the handle as possible.
You can easily check this on an unassembled blade using a simple PVC ruler. Place the ruler on the blade head at a 90-degree angle to the handle axis, so that the blade rests only on the edge of the ruler. The smaller the distance between the ruler’s edge and the handle, the lighter the racket will feel once the rubbers are attached — and vice versa.
Accordingly, a blade weighing, for example, 86g can actually feel lighter and more balanced after gluing the rubbers than a blade weighing 82g.
We’re talking about differences measured in millimeters, but they can significantly affect the overall balance of the fully assembled racket.
I’m not sure if I explained this clearly enough — if needed, I can draw a sketch.
