Yeah, well... Probably Chinese and Arabic scripts would be overkill, but (and maybe it's just my native-speaker bias) I don't think Cyrillic has a place among them. I mean, it's similar to the Latin alphabet, which has its advantages and disadvantages, but basically I think after a little bit of initial confusion you'd only have as much trouble as with your native script, in the sense that letters can be mistaken for each other similarly, like maybe "a" and "o" (handwritten)... Not that I'm suggesting that you should learn Russian... just wanted to clarify the matter.

Myself, I'm getting ever closer to plunging into the study of Welsh, due to my terrible job and feeling like I don't have that much time because of it as a sane person in possession of all my mental faculties... I'm thinking that if I make it through this latest stab and a kick at least somewhat ship-shape I just might take a whole day off and devote it to Welsh.

Oh, also, not sure how much I should go into this matter (out of fear of leading you astray with one more language), but I've found at least one pretty cool Dutch resource that I haven't seen replicated for any other language (to my great chagrin). It's a series of simple short videos with parallel subtitles in English and Dutch about learners and teachers of Dutch which gradually develop into a complex love triangle... or rather web... story thing. Look up "Heb je zin" on Youtube if you want to check it out... It's really long and actually ongoing, in season 2, I think...
