Being new to the design concept, I was wondering if anyone has or entertained the thought of keeping a variety of Pearl Free Floating Snare shells and a backup of posts to make shell depth/material changes to cater to the music or vibe being performed. Shell depths range from 3.5", 5" and 6.5" with shell compositions of brass, seamless aluminum, stainless steel, steel, phosphor bronze, birch, maple, maple/mahogany and mahogany. Just wondering if anyone takes advantage of this seemingly flexible way to have a number of snare voices at your demand. Also I assume that these shells have no snare beds and fit in the chassis ring atop the snares? Does the chasis ring that the posts screw into have snare beds on the snare side?
