Hello friend!
Ive had the opposite experience from what you described. The only times I have gotten hot spots with my bricks is when I use them without the disk in. My thought, and thinking about air as a fluid, is that air flow will always follow the path of least resistance. When drawing on the brick, the heated air stream goes through the herb that offers the least amount of drag to flow, thus focusing the heated air in one spot. In my experience, this is more apparent without the disk, because there is no delay in the heating of incoming air, you are inhaling a very concentrated amount of heated air.
With the disk, however, you are able to delay the source of heat so that it can mix more thoroughly with the air that enters the fresh air intake. It creates a more consistent heat source that you draw on, and even though the air will still flow through the herb on the path of least resistance, the source of heat is more even and steady. This is coming from someone who uses the disk always, and always a large triple flame torch. The key is creating even, consistent heat.
Doesn't surprise me. I've seen people with differing experiences as well and obviously depends on a lot of factors. I tend to use a single flame torch without the disc and angle the flame so it disperses within the heating tube rather than letting the flames go straight in. While this method eliminates the heat spots I used to get with the restrictor discs, it comes with the caveat that I have to pay attention more because it does combust more easily. As someone who has used SBs for years and got the temperature down, I definitely appreciate the faster heat-up more without the disc. When my friend or wife uses it though, they're more comfortable with the disc.
Also I'd like to add: This is a big part of why I really like the bent flame intake on the Runt. It seems to be easier to spread out the heat and just not let the flame go straight inside. The Junior for this reason I found to have different heat-up properties with its short, straight flame intake.
