Unicot is a bullet proof edge. its so easy to learn. keep at it and you will see. It sounds like you just need to practice. If your doing unicot , make sure your tape is.15mm and good quality tape. Get a good bevel that shaves arm hair easily. then add tape and go steady with 30 light laps on misty slurry. then 60 on fresh water. linen /leather. as some one said tilt your slurry stone and rub up and down your coticule. then ajust your slurry and keep it milky don't let it get any dryer or denser. read up on coticule.be in the sharpening acadamey. This explain unicot to a tee. Once you masterd unicot. then try dilucot , if that fails you just add unicot edge ad your there.

You may also need a 1k for bevel work if your coticule is slower with slurry. As your a beginner i would grab your self a 6x21200dmt. then go to coticule as you have . If your experianced enough you could use a fast coticule . I still would get a 1k manmade hone . i've heard the 1k kings are great , i use 1200 /600 duo dmt.
