#1 I wish I had Bill's wages! Mine where much higher!
#2 I never really wanted to see my personnel carrying wall units, My personal tastes ran to much larger wall units that we machine set.
#3 Unilock Sennia stone would think has a higher angle of friction than any wall unit that I know of unless you go bigger to the Dura Hold system.
I guess I'm the only one around that used a Base Maker to install wall units, wait if I remember right Bill used one when he was here in Illinois. It made base installation much faster than the old pick up and pound and scrape method. I also used mini excavators back in the early 90's to install walls while everyone else was hand digging or using a skid steers. We had our first laser back in the late 80' when the price was over $5000 then now you can get one for under $1000 that does more.
The one thing about retirement is you remember the old days when things first came out.........................
