i do. i have added 20lbs in the last 6 weeks using it. like rodja i do a westside template. the only difference is i also use block periodization. i do 4 weeks on accumulation, deload, 2 weeks on intensification, rinse and repeat.
during the accumulation phase i do as many alternate variations as i can. on DE day i bench with bands and alternating grip. ME day is where i do a different lift. i am using floor presses, incline DB, and incline close grip for the variations.
the intensification phase i mainly just bench. as i get stronger i may start using heavier bands or chains if i ever get enough.
i think the hardest part is figuring out what lifts directly and indirectly effect your bench. i follow the advice given to me to do what you suck the most at. close grip and incline i suck the most at so i try and do those more often then anything. i have talked to people that have done westside for years and the exercises that help can change in time as your weak points change. i know right now my overhead press goes up my bench goes up. others i train with can have their overhead go up and their bench go down. one guy when his bent over row goes up his bench goes up and another when his floor press goes up, etc, etc.
