Default Proline 2WD closed cell front inserts

I have used the JC front inserts for indoor clay track. They are firm but too firm for outdoors. Will these be just the right amount of softness to use outdoors? I would like to use cc inserts because of balance, consistency and reusability. Thoughts?

Since I'm probably the only person to run them so far, I will have to answer. They are definitely softer than the rock hard JC stuff and should be good outdoors. They are about the same hardness as our other 1:10 scale closed cell foams and should work great indoors as well. I ran them outside at the PL test track and they performed better than expected.

What we really need is a closed cell front foam with exactly the same characteristics of a Losi stock (yellow) rear foam that doesn't wear out so quickly..

Foam is composed of millions of bubbles in a material. Open cell foam has cells (bubbles) that are not complete so air flows through it. Open cell will compress more but wear faster because of it. Closed cell is the opposite, it won't compress as much because the air bubbles are trapped. It lasts way longer but it's been difficult to make it soft enough for 3 1/2lb electric cars.
