Dynapad or Dynyaliner

[73camarols1]

I'm cover the whole inside of my 2nd gen camaro in dynamat xtreme. What is better to use as a second layer on the floor dynaliner or dynapad? It looks like DSE uses dynaliner from there build pics. But it sounds like Dynamt recommends dynapad. If you are using dynaliner are you using the 1/4'' or the 1/2''? Thanks for the help Bill
