My fave SM event is the Atlas Stones. I am sure you will smash that with such a fine deadlift that you posess.
It seems lowbackitis is going around these days. I hope some stretching and rolling is helping sort it out. That's what I have been doing and mine is getting better.
Really glad you had a great time at the Arnold. carnivore candy really caught my eye as well . what a great name they came up with
