I don't know where most guys are. Pete spends a lot of time here. Always provides great input. Could be summer vacations.
In our phone discussion I believe I mentioned several times finish durability is about the same with the medium to higher quality brands. Some obsess over it far too much. They're all going to scratch, ding and dent.
Frankly you'd probably be better off going with a sand in place floor and apply an oil based finish. Many of today's prefinished hardwoods etch with scratching, or become more visible. The older types don't, or the ones prior to aluminum oxide and such.
Pete can probably help better than I on a good oil based finish.
Unfinished engineered hardwoods - maybe even a wire brushed one
