Which Super Clamp

I have looked up the Manfrotto Clamps and I am trying to understand the difference between there 2 Clamps, has anyone used these clamps or no the BIG difference?

I have been to Manfrottos website and does not say much, and I also did a search on here....

Manfrotto 035RL Super Clamp with Standard Stud @ $26.99

Manfrotto 635 Quick Action Super Clamp @ $35.99

I'm thinking the 2nd one is heavier duty than the first one>

Please chime in, with any info....

thanks........

HEre's a past from the link you provided on the first one. Look under features.
