I've been researching all sorts of different sleeping pads trying to find the right fit for me, but with no luck. I'm hoping someone here has some suggestions to help me find what I need/want

About me:
I'm a newbie that has aspirations of building up to week long trips in the Big Horns of Wyoming and possibly even Wind River area in Wyoming during summer months. I'm wanting to stay relatively light, but ultralight isn't neccessary as I'm more of a "hike to camp" type guy as opposed to "camp to hike" type. I forsee myself covering 5-7 miles per day. I really like the idea of the neolite, but tried out the large (25 inch), and I found that it's just a little too small. I'm 6'4" with very broad shoulders. I wear a size 54 coat. I've tried a 30 inch pad, and thought it was a nice size, but it wasn't nearly as light as I'm wanting to find. I want to say it was in the 5.5 pound range! Are there any qulity, light weight 30 inch pads? If not, are there any creative alternatives out there?
