Birds Eye Maple is what the wood in the floor is.
Zip Ties are really the best way to go for seperating hoses. Like someone said above the stainless line will wear the aluminum clamps, Adel Clamps mean drilling holes, drilling holes means places for water to get inside the wood/floors, and when you go to work on the boat its alot easier to snip zip ties and reinstall them later than it is to screw around with allen wrenches and 30 hose seperators. It's all about function when it comes down to little stuff like that, the zip ties may not look the absolute best, but are no by no means an eye sore, and they perform the best in the long run.
