I am also doing hardwood floors. Using a Brazilian hardwood called Koa. It is 60% harder than Oak. The advise I got was staples are twice as likely to give a bad shot having two legs and a bridge to seat flat on the tongue. He said the nails are actually cleats, which unlike a nail have series of sharp extrusions that help in the holding force of the cleat. With the glue that is holding the cleat strip together for loading ease this glue melts by friction also increasing holding power. Remember I am going to use a very hard wood and will be shooting a 2 inch cleat. I have picked out this gun for purchase. It is more money at $ 520 but if you buy the best it is sometimes easier to sell the best. 445AMP Powernail pneumatic can be had on ebay with free shipping.
