Early on with Cooper's cans,I made a hop tea first,but used an ounce or two. Then brewed the beer.
In this case,Cooper's IPA is the English version. More bittering than hop bomb as our version is. So the .6oz would be ok to keep it more English. I can't remember if they dry hop theirs,but you could go ahead & dry hop 1 week.
