As promised, here's my analysis: I ordered the #8 sewing needle and the #26 Tapestry needle
The #8 sewing needle is a larger sewing needle than I like to use (I prefer #10's), but still works ok for general sewing and some of the larger (14 or 16 count) monocanvas pieces. I also tried it on 32 count evenweave project with a loosely-spread design (ie lots of open room), but it's a little to thick in the haft, and the eye would catch about 1/3 of the time. It never caught on normal material you'd use for clothing - I tried it on both heavy and normal-weight materials.
The #26 tapestry worked great on 28 count hardanger, but was too big for a tightly woven 32 count evenweave. I worked 4 solid rows in TW's Mermaid with it and had absolutely no problem with it. Which says a lot considering the amount of confetti stitching she likes. It works OK on the same 32-count design I tested the #8 needle with.
Both needles were very easy to thread, and the only time the eye caught is when I used the needle on a piece of needlework fabric too tight for that size needle anyway. I liked the #26 tapestry enough to order another one.
I also sent an email requesting a #28 Tapestry and a #10 sewing needle with a very sharp point. We'll see.
