Replying to S rails

Oye,
So today at sunapee (NH) i hiked their S rail about 30 times trying to get the whole thing and i gotta pretty damn close.  I was able to get around the first C and about 3/4ths of the second.

Any tips on how to master this rail?  Should i go in with a lot more speed then a straight rail or less? also i have been jumping on prretty straight and was wondering if it was better to jump onto it from the left...  One more problem i was having was that after the first C my body tended to straighten out forward and the rail would go between my legs or i would fall off...

Any tips would help!

Heres the rail
