If I were up to and capeable of ripping/drilling/countersinking my own deck, there are a lot of very pretty woods out there to pick from but doing some research and that is beyond my abilities and patience level. I did consider doing a pine/oak floor now and using it as a template for an upscale option in the future. I just think a precut kit is my best option at this point.
Disappointing news on the wood finish though. What about rubbing in some oil every year or something? Not so much worried about warping or cupping, the rub strips hold it down pretty good.
