Man, none of that’s necessary, it’s a GG Elite, it not a Horween HOH tank! Should break in really fast with just some catch.I would advise you put some Nokona glove conditioner on it, put a ball in it and stick it under a mattress at night for a couple of weeks. Play catch as often as possible until it’s easy to close and feels good.
You can have it steamed if you want to spend $15-25 but it’s not really necessary. Just be sure to steam before you put conditioner on it if you go that route.
