Modifications...Again

I thought/hoped this was going to be a straight forward knit. I haven't had one of those yet and was pretty excited about it. I am refering to pattern #34 from Vogue Knitting Fall 07.

Unfortunately I couldn't find a picture anywhere online to present here so lets just say it has major cabling on the front, back, and a line of cable up the sleeves which cross over at the neck. I'm knitting it with Jaeger Roma which is a bit stretchy and has an every so slightly larger guage. Its pretty beautiful so far but I'm starting to really loathe the 12 sts cable portion (two of them) right in the middle of the front/back. Its just too bulky! Why oh why couldn't this be simple. I am wondering if its because the yarn is stretchy but am more inclined to think its just too large of a cable to sit pretty. Now I have no idea what to do.... :( Any suggestions????
