hey i train wsb. i know that bar speed is the important part, but i was afraid of thinking i had 100 pounds of tension and wind up with 300 and injure myself. this question was mostly for my safety but as a side note just wanted some info about what people found for percents so i do get smashed and i figure those who use them would have a good idea of how they arranged their workouts differently with them due to the different tension.
