Having recently worked on a couple of bar tape projects I was wondering what members thought about the various brands of cloth bar tape. No cork, plastic, vinyl, bat skin or other materials, please.
Here are my observations:

Velox, Tressostar, Tressoplast, etc. : the standard French stuff I used back in the day and still do on occasion. Thin, fairly flimsy and too short. It's serviceable but there are better options these days.

Toshi: A recent project left me looking for a suitable DARK green cloth tape. The Toshi showed up looking much like the Kelly green available through Tressostar, etc. With shellac, I found it didn't go as dark as I was hoping for. It is quality tape and the length allows a nicely over-lapped wrap all the way up the bars. It seems fairly thick and "comfy".

Greengrips: On the recommendation of a couple of forum members I ordered some dark green from these guys. I will say that the folks at Greengrips are very friendly and helpful and I admire what they're trying to do. I found their product to be lacking, however. The color of the tape didn't quite match the color swatch on their website, There is no actual photo of the various colors. Just one color shown and the rest are small color swatch boxes. I found the color to be muddy and not rich, undoubtedly the result of dyeing over natural with eco-friendly dyes. I will say, though, that after applying shellac, the color darkened up nicely to a deep British Racing Green I was looking for. My main problem with this tape though is the construction. It is wider than other tapes, about an inch wide, but too thin. The tape distorts and has a tendency to want to lift an edge as it is stretched and pulled tight and the narrow, quarter inch wide strip of adhesive on the back doesn't help matters. The weave is just too loose and the fibers too light. I understand they have come out with a thicker tape but I think it is going to be way too wide , an inch and a half?! ...to be practical for making clean bends around corners on drop bars.

Newbaum's: While not available in the very dark green I've been looking for, Newbaum's is available in an impressive array of colors. It is narrow, at 3/4 of an inch, but it is thick. Very substantial with a nice feel to it, and tightly woven. The best feature is the length. Ten feet, which allows you to wrap as tightly as you want to and not worry about running out at the end of the wrap. Newbaum's gets my vote for the best bar tape I've tried.

I've not tried the Viva product from Jitensha but understand it is very nice stuff.
