WFD and Hammer Problems

I am a lightweight and I am having a hard time with my form with wfd. With the light weight I am doing better at it but with heavy I find myself throwing myself around rather than the weight. I tend to get off balance when I do the two-spin and the weight pulls me. What are some things I can do to help fix my form and build my spins back up to throw bigger?

Also, with hammer, I'm having two corresponding problems. I'm pulling myself off balance trying to get good spins and right when I'm in the groove where I have a solid control and good rotation on the hammer I start golfing about every other throw. How can I get a better rotation that will meet the middle ground?

Thanks for the tips! I'm competing on the 28th and hopefully I'll have some vid. to show for how I'm doing. I saw a bunch of pictures of Eric Frasure throughout his spins in WFD at each step and I've scraped together some ideas on how to try and use momentum to my advantage more.

I've got a question about this.. I met with college throwing coach (mainly for shotput but he also gave his input on hammer as well) this weekend and he had me accellerate on the upside of the orbit rather than on the dowside of the orbit and I hit a 4' HH training PR of 91' without spikes. My previous training PR was 87' and my meet PR was 88'11.75"..

his philosophy was that you want the speed increasing on the upside rather than the downside... I tried it with the light hammer as well and hit a 2' training PR..

anybody have any thoughts/comments to add to this?? I'm just curious as to what everone else out there is doing. I was previously throwing with all my on the downside of the orbit then adding power on the upside for my release.. but this seems to work just as well with less balance issues..
