Are there any sets without a lot of fluff?
While nearly all sets these days to include a certain number of parts that you may be referring to as &quot;fluff&quot;, the Classic line has the highest ratio of more typical bricks and plates that you may be used to and has a number of sets at quite a few price points that may be useful to you and are available both direct from LEGO and from many retailers.
A note of caution over your classification of those &quot;fluff&quot; pieces though: You may find if you progress to more advanced building techniques that many of those pieces you currently disdain are absolutely indispensable to accomplish some very interesting effects that are simply not possible with standard bricks and plates. Don't discount the utility of a part simply because you may not be familiar with their usefulness or that they may not be immediately related to your current project. A fairly common term in the community is NPU which stands for New (or sometimes Novel) Parts Usage and stems from people being very creative with parts that might not immediately seem to have any other purpose than their basic form might suggest, and has led to very interesting and quite stunning results.
