New Response to 1.e4

I want to expand my opening repertoire.  I want to try a new response to 1.e4.  I have been playing sicilian for a long time, but am beginning to tire of it.  I was thinking of trying either the French, The Caro-Kann, or the Modern Kingside Fianchetto Defense.  Which of these responses to 1.e4 do you prefer and why?  What are the positives and negatives of each as you understand?

I prefer the french as it offers me choices that are both solid and dynamic with chances for both sides.

It is also rather closed and fits quite nicely with my rather positional style.

which sicilian are you playing, and why is it not suiting you anymore? that may be a good start.

I've been playing the 'old sicilian,' playing 2...Nc6.  I very much like the position I get when white castles short, but in positions where white castles long and pushes pawns on the king side I usually feel overwhelmed by their attack and strugle with my minority attack on the queenside.  I feel like in most of these sicilian games I, as black, am usually very constrained early in the game (with bishops on d2 & e2 and pawns on d3 & e3).  I dont nevessarly mind this lack of space since I often get preferable pawn structures in the long run, but it seems to give white time to develop his pieces, castle long, and start his king-side pawn push that eventually suffocates me.

the French,Caro-Kann,Alekhine,Scandinavian,and some notable gambits (Icelandic,Latvian etc) are great alternatives to the Sicilian.

I am leaning toward Caro-Kann but I am completely unfamiliar with it.  What are its advantages/disadvantages.

I am starting to explore the caro-kahn myself.  Nick de Firmian describes it as "unpretentious".  Similar to the french, but it doesn't lock in the dark square bishop.  You play for straightforward development without causing any positional weaknesses.  As de Firmian also notes, "the minus side is that white is granted more freedom of movement.  White's challenge is to make use of his extra mobility before Black completely frees his position".  (Paraphrased from MCO.)  Its very solid, but you need to be content with slow, steady improvement of the position.  If you like to go screaming across the board while white counterattacks on the opposite wing (i.e. the Sicilian) its probably not for you.

yeah, changing to the hyperaccelerated dragon might be the best way to discriminate against opposite side castling and the typical sicilian storm.

but caro is fine to. not much passion but it gets the job done
