TCLynx: I went there and found my "recently designed" system. I have been reading, learning, and sketching designs for about a year and a half, now. My computer skills are so poor that I haven't been able to figure out how to post my drawing. After seeing my same system already sketched, I am confident it will work. It also gave me some ideas on raft systems. Pictures ARE worth a thousand words! Thanks for posting, because 6+ years after you did, I got to benefit from it.
