Test E to prop/ Prov/Hairloss/and bloat question (Slingshot)

I am doing the slingshot with reload/deload protocol from Ronnie...

Currently on 500TestE/400EQ, with 50mg prov to keep the bloat down. Bloat shows really badly on my face. I am 4 weeks in and noticed Prov to increase my hairloss (DHT) as I am prone to MPB. I am going to stop Prov and thinking of switching to prop to counter the bloat. I also take propecia ED so that should help with hairloss from Test

My question:
1. How do I switch to prop, after how many days from the last TestE Shot.

2. I was thinking 100mg EOD, would that be roughly equal to 500mg TestE? If not then how many mg of prop?

3. During the 2nd reload, per the program, I was going to up TestE to 750mg/week, how much will that translate to in mg for prop pinning EOD

OR

4. Should I not worry about switching to prop and just drop Prov? Will EQ help with bloat and staying hard and vascular. 1st time on EQ

OH and I am also taking HCG 500iu/week through out the cycle

Thanks
