Yes the TT TX90 is just below a 100g, so very lightweight for a steel shaft. It's also mid-bend point.
Since you live in Ontario, there's a shop in Waterloo called golfquip at
www.golfquip.com
Prices are pretty good (though I can find better prices in the US, but there's the border tax problem), and they distribute Dynacraft products. The guy is pretty friendly and trustworthy. They also have a forum, though replies might take some time.
Anyways, if you need help or tips on clubmaking, just ask. I'm even considering making a little guide for those that are interested.
