Very much so. Lois should be a CNN reporter. A Suzanne Malveaux or Campbell Brown. (I must say I love that Erica Durance as Lois on Smallville). But to quote an episode of MASH,, "Lois Lane-- she always gets kidnapped, right?" For all her role breaking, she always gets tied up (and it's always kind of reassuring there's always a beautiful girl to be rescued by Superman).
Well they kind of behave like watercolor which is nice. The ink seems to stay a little wet for a time, and blends with proceeding tones you lay over it. However, unlike watercolor, the inks from these markers do set, and aren't really re-workable in the same way that watercolor is. I imagine this could be seen as both a strength and a weakness.
As for whether they're worth it, I can't say. I've worked with sketch markers before, but have always been disappointed by them, feeling the pens a bit too clumsy and short-lived to really be worth my while. These feel a lot better on the page, and can be used in a vary painterly way, which I like. The nibs also seem to be pretty durable, and it's a big plus that you can re-fill the inkwells on their pens, which are archival. So, lot's of plus's.
They are expensive however, so if price is an issue, it's probably best to just stick with watercolor or some other cheaper medium. As for me, the jury's still out. I just like to experiment.
