Be carefule with the plastic blades as they are notorious for boom strikes that destroy the tail boom. Also with the plastic blades your are more likely the damage your rotor head assembly in crash or mishap, because the plastic blades won't break like the wood.
Most pilots find it cheaper ($8 @
www.helidirect.com) and easier to replace blades versus the other parts of the rotorhead.
It's too bad they have none in stock at all. I am also using the plastic flat bottoms and have crashed em pretty badly multiple times (every time). They are still in pretty good shape and I havnt gone through any booms or head assys yet. Skids well thats another story... Just ordered my superskids today to hopefully resolve that. But yea

--}--{ has the right idea if you don't want to break a part stock up on it.
Also I am going to give this a shot and see how they work.
