Princeton synthetic sable one stroke brushes

My progress with the cat and bubbles are at the stage that probably no one'd care to see, including myself. I needed to do something different, so I played with the new brushes I recently bought.

I love those Princeton stroke brushes our teacher got for us when we first started with watercolors; they carry water and color well, and they are easy to handle. I use them all the time. After seven years, they are in a sad shape; time to get replacement.

I found Robert Simmons Sapphire stroke brushes at the local Hobby Lobby store, and absolutely love them, especially the 1/2" one.(the 1/4" one does not hold up as well) but I want a larger size that the store does not carry. I looked up online for it.

I did not find Robert Simmons Sapphire stroke brushes, but I found Princeton synthetic sable stroke brushes with the larger size, so I placed an order for them.

I was disappointed when saw them, They are so thin compared with the old ones, that I doubt their water / color carrying ability.  I tested them on the pages of a watercolor sketchbook, and found them alright, not as good, but alright. Because they are thinner with less hair, it's easier to get sharper edges.

I am still looking for better stroke brushes though.
