And becasue you seat them so damn hard
To the OP - it's personal preference. I find the wallnuts more versatile due to the groove. They definitely bite more easily than rocks, but I find that if you seat them gently they neither fall out or are difficult to clean. I used to have a set of classic rocks but sold them - sums it up for me. I now have a mix of wall nuts, offsets and peenuts (which are ace btw).
Cheers.
