TweetWell, it seems a bit short for the Test Cyp...by the time it's kicking in the 4th week you'll be off two weeks later.
I think you should run it for at least 8 weeks and you'll probably get better results off of 10.
My suggestion is this if you want to keep it fairly short.
Weeks 1-8
500mg Test Cyp
Weeks 1-3, 8-10(11)
100mg Test Prop EOD
Weeks 8-11(12)
Winny 50mg ed
Just 2 or 3 more weeks total, but the results will be better IMO.
