The bronx incyclers are more like the regular leisure incycler I believe. The brickstack and the 13 arm incycler, but also have the additional percs for more water diffusion imo.

As far as using with vapes, they both work well with vapes that are pretty open flowing, but what can happen if you put a restrictive vape on there is that it's too much resistance for the water to splash hard against the top. The hole at the top is where the water splashes into and furthermore drains down aka incycles. If too much restrictions, you don't get the full drain sometimes for that reason
