Help me break through a wall please!

Are there 50 M sprinters who don't use shoulder driven strokes? I know some of the 100M guys like Magmessun use a hybrid of shoulder and hip driven. I wish there was some good high quality footage of Alexandre Popov's stroke. I always considered him to be my hero, and I'd love to emulate his long, loping stroke! Last Friday was my final meet for the year. I swam a 24.55 long course meters, which isn't bad considering my PB for LC meters is 24.40 which I set when I was 17 years old, training 50km a week, Next year I'll keep working on my stroke and train a little harder and see if I can go faster. At this stage, I'm finding swimming really good fun. I've made a lot of friends through masters swimming here in Japan, and I think that having fun is the most important part.
