Sounds like you either have a great trainer/mentor or have learned a lot on your own. That training sounds great.
I used to train at a gym where John Parillo would bring in a powerlifter of his and I would train legs with them. Steve, the guy he was training, was like you young and strong. He competed in the 242 class and was quite short and compact with legs that looked like tree stumps. His big lift was the squat and he was putting up about 750 with a suit in competition. Last time I saw Steve he had a falling out with Parillo and was going to go into Pharmaceutical sales so I dont think he continued to compete. He talked like he was getting burned out on it and there was some hint there of him not wanting to take all of the performance enhancements necessary to compete at a higher level.
I can say from training legs with him that training for powerlifting is a whole different thing than bodybuilding. Those leg sessions were freakin brutal! Lots of respect for the powerlifters..
