After getting up to the timed S&S standard after about a year and a half, I did a round of ROP just to see what it was all about and absolutely loved it. The military presses are a whole different animal and I had to start all the way back at the 16. After working through the 16 and the 24 with ROP, I decided to give A&A a shot, which also was a great new challenge - worked up to doing 200 snatches with the 32 in a single session. The TGU I've kept through pretty much all of it as it really does wonders for my shoulders.
For the last two years I've been running 2-3 month a cycles of S&S, A&A, and ROP (falling back on S&S when I the other two become a bit too taxing), along with either running or stationary biking for aerobic activity 3x a week for ~45mins or so. Never felt better in my life. I'd highly recommend giving ROP or A&A a shot for a season and see if it benefits you.
