Hmm, probably the most linear of them all is the K2. It comes with a very dense sponge, it has 0 pores. However it is quite a fast rubber. Super linear and stable but maybe it's not the best of these in touch play.
In touch play the Rakza Z, Golden Tango PS are super good (probably the K1 too), however they are not linear. They hold the ball back which is why they are so good over the table. Unfortunately if you start hitting hard you can feel them holding the ball back even more. So if you wanna use these you need a fast blade. I guess a Viscaria caliber blade which you have is the minimum. These are quite heavy rubbers too 53-4g cut, while K2 is 49g.
I would avoid the new C-touch rubbers, their durability is appalling. At least C2 and Dragon Grip are, and I seen someone post K3 pics here and that looked like a bad joke. Also the C2 and Dragon Grip slip the ball (Joola Flash).
Just to offer some balance on this - I have two sheets of K3 in use and one is 3 months old and well used and is showing no meaningful signs of age or performance drop off.
