You are fine using teh 208 for linning, but it's also a great brush for brows. The 266 is a brush of the same sort imho... and can also be used for brows and linning. It's indeed thicker than the 208. Hope this helps

This is exactly what I was going to say, I was using the 208 with my Fluidlines before I knew better & it was soooo harsh on my eyes! Now I use thr 209 & I think the 266 is best for brows.
