And a knot/lump and unusual shape? Esthetically, I like the smooth clear ones, but I don't know if those trade sensations for looks.

I dropped all my toys in the garbage bin because they were old as fuck and I want to start the new collection with a basic one. I prefer it on the expensive side, so it will be only one, but properly researched for now. Maybe next month one with a knot, or whatever unusual thing I find desirable.
