Yesterday's brew day was better than Christmas for me. Had a friend over to help out while our kids played in the beautiful weather, brewed a cream ale, grilled beer brauts, and drank some cold ones. Doesn't get much better than that on a Saturday afternoon.
You went metric and imperial!! My head!! :drunk:
I am still pretty new too, but from what I've read about this on here popular opinion seems to be that that is not enough room. I think you're better off using 6.5-7 gal bucket.
A tip that came with my kit that worked very well was putting the LME bag in a warm water bath for several minutes before putting it in the boil pot. This really helped in getting almost all of the LME out of the bag.
