Foam type for celestron 9.25 xlt sct

[dillon80uk]

Hi guys just wondering if anyone can help me please to choose some foam for storing and moving my celestron c9.25 scope.

I have just bought a flight case to accommodate the scope but while browsing for foam sheets it’s a mine field I had a sample of shadow foam sent out but it seems really stiff and I’m afraid of breaking the corrector plate it seems fragile if I accidentally bang the flight case it might transfer the shock to the plate. thanks in advanced.
