Hi All - I thought I had done my homework but...

In searching these forums and the Internet it seemed the best stem for my Panasonic to allow me to raise the handlebars would be the Nitto Technomic. I've even seen numerous pictures of bikes with the Technomic stem towering above the head tube and the handlebars 2-3 inches above the seat height so I ordered one.

Unfortunately, it doesn't seem near as tall as I had hoped. At max extension I can get the handlebars about even with the seat height but no more and that's still allowing the nose of the Brooks Champion Flyer to cause numbness where I'd rather it not. I measured the Technomic and it is 180mm from the bottom of the quill to the center of the stem extension with about 105mm above the max insertion line. Based on pictures I've seen that seems a bit short. Do I have the wrong model? Is there one that is longer than 180mm? My other options would seem to be adding one of those adapters to raise the stem which looks pretty ugly or loose the Brooks for something without that problem (Selle Anatomica maybe?).

BTW, I have a Brooks Professional on the Bottecchia with about a 2" handlebar drop and no numbness issue there and had a Brooks B17N on the Panasonic previously and no problems there either but it was flat and did not have the "hammock" shape that forces you to position it nose up to keep from sliding forward.
