What brands use round cores?

[asberrys]

DR says that round cores are rare. Most strings have octagonal cores.The corners of the octagons grip the wrap better and I would imagine keep the wrap from slipping and help the string last longer.
What brands are comparable to Fatbeams then?

DR makes the most roundcore strings I know of. HiBeams, Sunbeams, FatBeams, and ExtraLifes are all round core strings.

I haven't taken a look at them, but I think my Circle K's might have a round core.

Pretty sure Circle K are hex core.

Pyramid, Dean Markley and Newtone beside DR off the top of my head. Sfarzo makes something supposedly unique which they call rouded hex which implies some sort of hybrid. Feel and tone of roundcore DR sets I tried on my guitars was nice but they are susceptible to unraveling during installation so watch out!

Fender's 8250 are round core.

[Jaco who?]

Pretty sure the R. Cocco strings are round core, but their website is annoyingly vague. Anybody know for sure?

TI Jazz Rounds and Flats are round core. Past that DR are the only other round cores that I have played or know off the top of my head.
