I have tried many of the colors. I didn't care for blue bahama but then I'm not much of a turquiose ink fan. Most turquoise inks (BB included) are too light for my tastes. Haven't tried Skies of Blue. Cobalt is my favorite Levenger ink and one of my favorite blues in general. Someone said that Levenger was going to change manufacturer of these inks - if you really loooove cobalt, you might want to get more than one bottle.
or not.
I have two things of theirs that I have found indespensible:
1) International pocket briefcase. I love this thing and it is basically my daily wallet. it won't hold a checkbook but I rarely use one these days except for paying bills. So it's great for carrying cash, a few cards, license and plenty of 3x5 cards for to-do lists and quick reminders. Their 3x5s are IMO, hands-down the best out there. I've tried other brands and they feather or are just not as smooth. And when bought in bulk, the price is really quite good compared to buying little packs of 100 at office supply stores.
2) a Junior size Circa notebook. Though I was very lucky to get mine on sale at a ridiculously low price. I probably would replace it at full cost if I had to though. It goes everywhere with me for more extensive notes. I use my own paper though - I found the circa paper a bit flimsy for my heavy inks in free-flowing nibs.
the other Pocket Briefcases are just as nice I'm sure. All depends on your needs. If I were working I'd probably just use the Shirt Pocket Briefcase.
Some people love the Notabilia. As far as I know, they're decent notebooks if a little overpriced given what they are.
I don't recommend the Stanley as a journal. The paper is a bit thin for FP ink. I do have the small Stanley with agenda insert though and I like that. But I don't work full-time so I don't need a large agenda. Just something to keep track of my days. The leather on the Stanleys is very sturdy. Still - up to you as to what sounds best. I guess if it were me with what I already have - I'd try the notabilia or Circa. IMO, for writers these are the most practical Levenger products.
oh.. their notepads are very nice but you need to have a use for all that margin space. sometimes I do, sometimes I don't. I'm still looking for a replacement to what used to be fully ruled Levenger notepads.
PS - if you confirm the Cobalt thing - please let us know.
