Ttokkoyo Deca is excellent gear as for the IP Winny can't say I know enough to give you advise/opinion on them although I have heard nothing but good things.
Now with stacking them I would throw in some test for best results try this:
Weeks 1 thru 10 Deca 300mg/Test 400mg to 600mg
Weeks 5 thru 10 Winny at 50mg e/d
Now if you don't want to throw in any test, but I still think you should seeing that test is the basis for any good cycle, then run the Deca at 400mg a week.
As for what you can expect in means of gains we are all different in how we react to different gear, but just to give you an idea I just finished a Deca/Sus/Winny 10 week cycle and gained a soild 15-20lbs. Good Luck!!
