I don't like to machine quilt hi-loft batting. It is harder to work with and would make SID even harder than it is. (I don't do SID anymore because it generates too much anxiety in me, and the inevitable deviations from the ditch drive me crazy!) Puckers are also much more likely when machine quilting high-loft batting.
If you want loft, my suggestion would be Hobbs Heirloom 80/20. It has a higher loft than many battings but is still reasonably easy to machine quilt. It is also a very soft batting.
