Bullseye sells 8-9 mm rod that gives a little more flexibility in size
Schott makes glass that is compatible, and if you're willing to order late quantities, you can get large diameter rods. >1"
Brazee st studio, near me, runs a hot shop with bullseye- so I know it's possible.
Boro handles make a huge difference in working stability.
