All record weights the same ?

What is a good record weight.

 Do they harm the motor, or put more stress on a direct drive motor?

 Technics sl1200 mkii from the mid late 80’s.  Removed platter, unscrewed top, removed spindle , and removed clamp,  wiped off old oil, fresh oil, blew out w compressed air, oiled any moving parts. 
 Put back together, and it’s smooth as silk.

  Anyway,...WHATS A GOOD descent record weight that will hold down the LP and not harm or put more strain on the motor.
