First, the material type, weight, and length for your personal preference, there is little noticeable difference between a QUALITY PV, such as from Marton Mills, and wool. There are cheaply made kilts with a poor quality PV to avoid, often mass produced and sold for extremely low prices. If you like wool, go with wool, 5 yard or 8 yard is up to you. If you like PV, then I would recommend a semi-traditional from USA Kilts.

I think the tartans you mentioned, American Heritage, German Heritage, County Kerry, and various other Irish tartans would be great options. There are also State/State Seal tartans, fashion tartans, and the various other non-clan options out there. If it was me, I would probably go for either County Kerry of a regional tartan from where you were born (even if the tartan is listed as unofficial for the region).
