Hi fit8585. I don't get around much here anymore, but thought I'd give you my 2 cents. I also have large legs, and am sure I'll never be happy with them.
I have a trainer who is built much like me - a true pear shape with large, prone to muscular legs. Essentially, my Cathe leg workouts are used maybe once a week on my light leg days - but even that my trainer cringes at. She has me go HEAVY 1x week. I mean heavy. I've said this in another thread, but think butt to ground squats in the 150 lb area. Walking lunges - I carry 95 lbs and do 4 or 5 sets of 25 reps. Now don't get me wrong - I've worked up to these numbers over the last year. And I've kept my diet uber clean. If you look at my pics you'll see where I did a figure comp last year - just to say I'd done one. I'll be doing one more - to be competitive, but I did post some pics that were taken just recently, and even I was amazed at how much thinner my legs look. And I honestly believe - from my own experience - that if you are built with large legs, the key to getting them to look "sleeker" is to work them HARD -- MUCH harder than the weights Cathe uses, but only 1x week. And I was SO reluctant to do this. I've learned a lot from the Cathe boards and the EC here. But it was only when I threw all my trust into a trainer with this idea, and worked to her knowledge, that I began to see results. She also says that it's a long work in progress. That every YEAR, with clean eating and heavy weights, she sees a little more imporvement.
It's not a quick fix, and may not be what you wanted to hear, but that's my experience. Good luck in your quest - it's a hard journey huh?
