You can add to the list of condom only studios/producers with no known bareback ties:

Colt/Buckshot
Lucas Entertainment
AMG
Latino Fan Club (I'm fairly sure on this one)
Massive
Lucas Kazan
Kink.com (I'm pretty sure of this one as well.)

Studios that are not producing bareback themselves, but are selling or profiting from bareback are:

Hot House- selling bareback DVDs on their website.

Raging Stallion/Pistol Media- They own GAYDVD.com which sells bareback DVDs. Gunzblazing.com their affiliate program promotes and sells Hotbarebacking.com memberships. Hardgayfeeds.com their webmaster content site sells HDK and TIM feeds. Sorry Brian but gotta be honest here.

Jet Set -Owned by Marina Pacific, one of the bigger bareback distributors

You can also add to the list every single VOD company, as they have all succumbed to the pressure of profit.
