Default Clutch TO Bearing Issue?

I have a clutchmasters stage 3 clutch and ap1 flywheel. I waited 500 miles for break-in. (longer then usual since it is a kelvar clutch).

I just started getting on it. When I shift at revline it makes a tiny squeak noise from the clutch not the pedal. Also the clutch grabs hard at revline, not a smooth engagment and shifting is just a tad clunky. Also the clutch grabs a little high not sure if this is normal for the clutch i have.

Thoughts? Does the clutch just need some more time to break-in? Anything potential issues? Could this be related to the Clutch Pivot Point and Release Fork?

After some research I think I know the issue....

Its not the clutch pivot point and release fork because this is not a pedal issue...

It seems it may be the pilot or TO bearing. I read this from another form which seems to describe my exact issue:

"'sqeeky' only when the clutch pedal is depressed when on a test drive would usually point to the pilot bearing or throw out bearing. The pilot bearing sits in the center of the flywheel as it supports the transmission input shaft on rwd application. When you disengage the friction plate from the flywheel the input shaft now spins on the pilot bearing, squeaking could indicate worn bearing or lack of lubrication, replace as necessary.

Throw out bearing could squeak with a lack of lubrication, but usually associated with clutch noise due to improper installation. This causes the bearing to be 'cocked' creating uneven pressure of the diaphragm fingers giving a funny feel in the clutch pedal. Lack of lube on your throw bearing/transmission input shaft may create a 'grabbing' effect because your bearing has a tougher time moving towards and away from the pressure plate diaphragm. Grabbing is when the clutch has a rough time dis/engaging usually associated either the friction plate hub (center) or throw out bearing not moving freely enough along the trans input shaft. "

Please confirm whether you think this is my issue.... I had a shop put the clutch in so i would assume they would fix an issue like this for free. Anything else I should consider?

So can a clutch job make your shifter feel a bit clunky? or am I just imagining this... As for the clutch, i drove the car some more and really it feels like nothing is wrong with it at all so long as you dont shift at or near revline.

Anyone at all???... I called the shop and explain the sypthoms. They are going to check it out tomorrow. I told him that the only thing I could think of is that maybe something wasn't lubracated properly such as the release fork, etc. At that point, he told me that everything was lubercated and installed properly.

I just worry because shops typically try to blame problems on something other then their install work to get out of covering it. I am not sure if this will be the case here, but i want to go in more educated just incase.
