Default "Clunky" Transmission

I'm getting driven up the wall by this silly issue, that may or may not even be an issue. About 75% of the time I shift into 3rd, it feels "rough" but it's not the kind of grind you'd get when you misshift. 2nd does it occasionally as well, and 1st sometimes (probably less than 10% of the time) feels like it's trying to lock me out, and I have to shove it into gear. At a stop, with the clutch in, it will occasionally exhibit the same behavior. I've tested the clutch, and it's not dragging. Whenever it isn't rough, it's literally perfect feeling, and literally falls into place perfectly smoothly. It seemingly happens at random. I've changed my seating position a bit, so my leg isn't as outstretched on the clutch, to make sure I get it all the way down everytime, and no difference, it just works great when it wants to.

I adjusted my clutch recently, the engagement point was a bit too low for my liking, but I made sure it's still perfectly within spec, and the master can still bleed. The issue was here before I adjusted, and it seems to have made no difference.

The 1st gear "shoving" thing happened after I changed fluid to CarQuest GL-4. The old fluid used to be smoother when I bought the car, but I don't know what it was, and I have a slow leak from the linkage shaft, so I need to keep it topped off, or it drops to about half the fluid height. I'm going to try Redline fluid in about a thousand miles, I'm tired of feeling like the fluid is at fault. 1st seems to be a smoother shift when I have the revs up pretty high.

It doesn't lock me out of gear at high revs, or low revs, or high speeds, or pretty much anything really abnormal, it just feels "clunky"

Is it something I'm doing wrong, or are my synchros shot, or is my slave dying (JasonY's suggestion), crappy fluid, or am I being paranoid?

Someone with more experience wanna try it and make me feel less crazy? I should have just told lawdogg to try it back when I met him, but I wasn't worried about it then.
