Gas check shanks can be short, with almost no space between the check and the bottom band, or longer leaving a lube groove of variable length.

Has anyone experimented with this? I can vary the check wall height using Disk Checks.  I was wondering if there was any advantage or best length.

I have read ...and it seems to work out in my experience where having a gap between front of check & last driving band edge provides room for lead accumulation from gas check scraping bore. Plus giving a bit more lube.
