Gary, congrats on the purchase! I am sure you will enjoy it.
I've been using the short version of sleeping pads for years, since it saves a few ounces. All I do is fold my hiking pants and maybe a coat for the area under my legs and feet. I have never wished for any cushioning in that area.
The only time this method would not work is when it is super cold (maybe around 20F, or sleeping on snow). You should try it.
