I am looking to side my house with real wood (redwood) siding.  Love the idea of horizontal nickle-gap, but I am concerned that water will get sucked into the gap and not drain out causing premature rot/failure.  I am in upstate New York and siding will have a rain screen behind, so I am not worried about water intrusion into the house.  Am I being paranoid?

Rainscreen makes horizontal siding easier, although vertical siding would drain water better.  Prefer the shadowline of nickle-gapped over traditional T&G with V.  Siding will be stained on all 4 sides before being installed.  Home is a ranch with 2′ overhangs.  

Thanks

Mike
