It depends on your goals. You might have guessed that mine are to reduce bf - even at the expense of muscle. In fact I wage a daily battle with bf!!
If you want to end the cycle looking more cut then I would suggest leaving the test dropped at week 8 or at least reduce it from week 8 to maybe 50mg a week until week 10 where you drop it altogether.
Forget the var and instead run Winstrol weeks 10-11 at 50mg a day with your tren and mast. or if you really must run var use 20mg of var alongside the Winstrol. Running 2 orals at that level for only 2 weeks at those dosages won't collapse your liver but make sure you give it a break post cycle.
It's definitely worth using the masteron as you outline past the tren so that's a good idea.
Beware tren is very very suppressive so I don't know how long you usually give it before starting pct but with that dose of tren I would wait 6 weeks after the last tren shot before starting pct. Even if you have a mere 25 mg in your system you will be completely shutdown so bear that in mind. People often start pct way too early after tren and end up doing it whilst too much tren is in their system. The result is a botched pct and no recovery !
As you are using the mast for most of those 6 weeks you can probably do pct 2-3 weeks after the last masteron shot (I presume it's drostanolone prop not drostanolone e)
