I have been on ROTK for about a month now. Now, I didn't snatch the bells the first grind block through as I really couldn't double snatch 32s, but I did my light day today with a pair of 24s and I definitely see how it just adds an extra layer. We'll see how medium day goes with the 28s, but I know I still cannot snatch 32s -- not yet. I like the extra eccentric you get by lowering them after snatching. Definitely felt it more in my back and shoulders.
If anything -- and I know some folks have written they don't like the snatch part -- it really spices things up with the snatches. Gotta admit, it's kinda fun.
