I'm installing new hardwood flooring in my house, and I was wondering if it's better to use nails, or staples. I see lots of air staplers out there, but I'm not sure of the durability of staples over nails? Also I noticed when tearing out some of the old flooring that there was rosin paper under the flooring, do I need to lay new rosin paper down, or is there something better now? Any advice of help would be greatly appreciated, because this is the house I plan on living in for a long time so I want to do it right the first time.
