UPDATE: I went straight to the SJ-250 and was able to get the job done. I'm going to run a few more knives over it tomorrow to see if I can duplicate it, but so far so good. Thanks to everyone for their help.

Swiping down = running the blade across
What you're explaining is what I'm doing, except for the edge refinement. I was pretty much just getting the burr off (that I could feel) and stopping/testing only for it to be dull. Do you think that's the only step I'm missing and preventing it from getting sharp?
Yeah... you probably just need to spend a bit more time on the leather wheel.
Have you watched Jeff's video on knife sharpening? He demonstrates it pretty accurately...

If you are searching for good instructional materials, the best source is the handbook. It was written many years ago by Torgny Jansson, the engineer who invented the Tormek. Unfortunately, Torgny passed away around ten years ago. Except for bits and pieces about new models, jigs, and accessories, the handbook has remained unchanged. The SG is well covered. Newer wheels, including the SB, SJ, and diamond wheels are barely mentioned. Nor has much video support been done with these wheels. That is one reason I recommend that new users stick with the SG.
Tormek has commissioned some outstanding technical videos over the years. The lathe tools DVD that Jeff Farris did using a SuperGrind remains an excellent training resource, as does the video that Alan Holtham did later with the DBS-22 drill bit jig. Jeff Farris also did some good shorter videos with chisel, knife, and scissors sharpening.
Beyond these, quite frankly, you will find most of the expert advice on this forum. I certainly do not include myself in the first tier of knife sharpeners, however, we have several on the forum.
One area where I find the Tormek information lacking is in grading for the most desirable grit for different tools. Tools like planer blades and turning tools cut a lot of wood between sharpenings. They need all the coarseness the 220grit SG can muster. Chisels are often used too long before being resharpened. Ideally, kitchen knives will require gentler sharpening. Carving tools should only need a delicate touch with a fine stone. This is the kind of skill one develops with experience.
Give yourself the luxury of being an apprentice. Do not expect to master sharpening overnight. With diligence and focused effort, your skills will develop. Do not become discouraged.

Welcome to the forum, CWS.
In my opinion, the best starting point is the SG-250. You will learn the most about its strong and weak areas be actually using it yourself. If you should encounter steel alloys that it does not handle well, at that point I would consider purchasing a diamond wheel. Others have differing opinions, however, for my money, diamond is the logical next step. Diamond is our hardest material. The blackstone and CBN are both harder than aluminum oxide, however, why not go to the hardest material? The Tormek and diamond are a good low heat combination. The cost difference is not really significant in the long run.
In my opinion (others will differ) diamond wheels have made the blackstone obsolete. My diamond wheels have cut well for me right out of the box. My blackstone has never cut well for me in nine years.
For knife sharpening, if you decide you want another wheel, start with the DF-250. It is the same grit as the DWF-200, the standard wheel supplied with the T2, which is designed only for restaurant knives. (The T8 is a much more versatile Tormek than the T2.)
