x2 on the Xlab torpedo. I have mine in a gorilla cage and works perfectly
I originally had the bontrager bta system, swapped out the bottle cage and fastened it to the attachment that came with the bontrager system and threw the xlab torpedo bottle in it. It has been secured further by a screw/Velcro. Used it yesterday and it is solid as a gd rock.
