I do like installing hardwood, having mostly maple and some pine flooring elsewhere in the house. All lovingly installed by me. I don't use rosin paper, however I glue and nail. I try to nail primarily to the joists and I plan every row for the least possible waste. For this job other than cutting around doorways I did not need to do a single cut. The trick is to organize all stock and first use pieces of wood that have multiples of similar lengths. Cant help it, it's the engineer in me. I also do the "racking" technique where possible.
