Enough difference that I now use half as much (re-post)
I was almost out of Texas Toast chenille so I bought some more from CAT (the only place I've seen Texas Toast). Robert carries #3 on the site but through a special order, I was able to get #5 this time.

As you can see, there isn't that much difference but I was having to double wrap most of the jigs I used the #3on, especially the 1/8oz jigs. The jigs below are single wrapped and they turned out alright.

These are double wrapped with #3
