Thanks all for the encouragement and detailed feedback, I really appreciate the time. Taking your advice into consideration, I dropped the Harmonaig and replaced with a uO_C and a Warps. Also, the Beads tip is very helpful so thanks for pointing me in the right direction there.

If there's any interest, I've updated the original link after some reshuffling and saved the rack for a comparison point down the road, we'll see how it actually turns out as it grows!
