To the OP if you have all of this and plan on running it I think Rick Rock and GymJunkie gave you two really good pieces of information. I hear what people are saying about kickstarting with prop but remember Rick said possibility to cause more aromatization hence you need your AI dosed correct or else it can cause sides (you want to feel your best don't you). As for Gymjunkie's comment on running GW throughout the entire cycle and PCT is correct and you will only cut much more effective especially after kickstarting with winny and not prop.
Now please consider this:
The purpose in my mind for switching esters is to increase the plasma levels and this is how it should work. I don't think kickstarting with prop is as productive as switching to prop the last few weeks of the cycle. Why is this you may ask? Well this gives a chance for the longer ester to diminish and the shorter ester to take over which prop is renowned for causing an increase plasma levels quickly compared to Enth or cyp which takes time to build. This why you can give a bit of punch going through those weeks 10-12 where myostatin might be trying rear its head.
This is just my opinion, I'm not a scientist but at this point I think I can say finishing with prop might be the better way to go. Re-think the cycle and possibly simplify the cycle and break it up into two separate cycles even. I find that throwing the kitchen sink at a goal sometimes isn't always the best course of action. The saying less is more is true and this is true in being able to listen to your body better in order to understand where you need to work on or grow more. Again just my thoughts
Cheers!
