Help Selecting from Available Mtn. Dulcimer Hourglass Plans

I am in the middle of one dulcimer build using a free plan I found on the internet. I suppose it is a teardrop except both ends are symmetrical. I would like to build a hourglass dulcimer. I don't want to start a war here, but I would love to hear suggestions for good plans that are available for purchase or for free.

My woodworking skills are professional. My instrument skills are a noob, but I'm not having any trouble with the first one. I'm just second guessing what it will sound like. :)

I am after something in the mid range, not too bright and not too muted (I forgot the word for less bright)

Thanks for any suggestions! I'm glad I found this forum and am looking forward to learning and sharing.
