I've never really thought about tackling technique since I was taught it. I just do what seems right at the time. I just pile in and nick the ball. Couple shin scrapes don't go amiss either. I never really spent much time on my feet, but my sliding tackles were almost all perfectly timed
Although, there was one time... it's tough to get sent off in kids' Sunday League footie, but I managed it, though to this day I swear I got the ball as the last man, even if the kid tripped and sprained his ankle
