I withdrew my question because nobody was replying, so I went ahead and purchased a stem (I was in a bit of a hurry). Now that I've started receiving replies, I regret deleting my post.

I wound up picking the Full Bodied Red Wine glass of the Schott Zwiesel Top Ten line. It seems to be analogous to the Vinum Extreme line by Riedel. I picked it because the lead crystal content in the Riedel Vinum/Vinum Extreme was cause for concern, and the S-Zs are said to be far more durable without sacrificing in performance (I can't imagine packing a Riedel into a suitcase or box without some serious insulation).

To elaborate on my usage for the benefit of future thread readers, this stem will not be used for serving guests. Instead, I will be using this one privately to make observations on bottles I buy for private consumption.

I probably should have purchased at the very least three glasses (one for Bordeaux, one for Burgundy, and one for Whites) but I am constantly on the move, so I didn't want to have to deal with the hassle of taking care of three glasses. Hence the compromising all-purpose Full Bodied Red Wine glass. Not sure if this was a good decision?
