In my current rotation, I do Kroc rows every other bench day (chins on the other bench day). Sometimes I'll do a heavy, low-rep (5-6 reps) horizontal row like barbell rows for about 3-5 sets, then go straight to the 100 lb. Krocs for 1 all-out set. Other days, I've done warm-ups to the 100s with 20/40/60/80 or 25/50/75 or even 40/70 for 8-15 reps per side, then the 100s to failure. I always treat each side at the heaviest weight as its own set, and may rest 3-5 minutes between left and right sides. The Y where I normally train tops out at 100 lb dumbbells, so I have to start benching at another Y location in town where they go up to 150. Last time I did them a couple of weeks ago, I hit 30 reps per side with 100 lbs, so I think I'm going to reset at 110 and go until I hit 30 reps again.
At this point, I don't plan to go to Raw Nats this year. I haven't looked into how affordable the trip would/wouldn't be, but the timing isn't so great for me. My wife and I are expecting another baby in June, so that may rule me out without considering $. However, if I got an invite to the Arnold Raw Challenge this year, you should definitely get one for 2011 if you hit what you're capable of at Raw Nats. Then I'll meet you next year in Columbus when I'm a spectator again!
