Help Consistent mistracking in the beginning of lp


Hi
I have Michell Gyro SE/HR power supply/RB 600/Shelter 501mk2/Expressimo counterweight setup.
The needle jumps/skips or sometimes locks in the groove during the first 5-10 seconds of playback then settles in but sometimes (rarely)it happens in the middle too on aggressive music.
It happens on 180 gr lps only and if the music is aggressive.It never happens if the record is thin or if the music is soft anf quiet.Cartridge setup is right and the table is not shaking when i lower the lift.
I don't even know where to look for the problem that's causing it.Please,help.

Overhang, I have exactly same problem!! And I am trying to isolate the cause. VTF is okay. Azimuth is okay. I did not think about 180 gr v/s regular 'thin' records. Come to think of it , in my case also it happens with heavier LPs. At first I thought, it is due distortion, or due to dirt and finally due to vibration. May be I will learn some thing too.
It is annoying as hell, perticularly after spending big bucks on the new set up!!
