Switchig from Test Enth to Prop mid cycle?

[Rebel Yell]

Test Enth 500 EW 14 Weeks
EQ 400 EW 14 Weeks
Tren ( 100 EOD ) 10 Weeks
Planning on doing Winny 50mg ED for the last 6 weeks.

I am in week 6 of Test Enth and EQ
and week 5 of Tren.

Was thinking of switching Test enth from 500 EW to Prop 100mg EOD along with my Tren for the last half of my 10 weeks on Tren.

Would that be cool?

What about the 4 week layover of my Test run, can I go back to Test Enth at 500 for the last 4 weeks.
( I plan on using a Finaprop product )

Thanks in advance.
