Pic/Opinion Request! 11.5" barrel w/9" or 10" rail

OK, please excuse the form-not-function qualities of this question. I have an 11.5" lightweight barrel on the way from DD and plan to pair it with a MI t-series rail. Based ont he carbine gas system, do you recommend the 9" midlength or 10" extended rail? Does anyone have an image of a 9" rail with an 11.5" barrel? I've seen several 10" rails over 11.5" barrels, but I don't know if I've seen a 9".

I'm leaning toward the 9" for asthetic and weight-saving reasons.

Opinons are welcome, pics are appreciated!

If you can accomplish what you need to with the 9" rail, go with that. I have a pair of uppers using 9" VTAC/TRX rails, and that seems to work plenty well.
