Might I suggest "ease of use"? I love(d) my N20 because it was well laid out. Most of my collegues agree. Only issue they have is that some of the control lines were hard to handle (especially in a blow).

Also, a lot of minor control lines were customized by teams to run back to the driver (crew had too many lines to worry about already). Maybe opt for that layout, too...

Figure out some leverage on the spin sheet, up the ratio on the downhaul, and a lot more people would want to drive them...
