Flagstones and Hallowed Fountain

[Matt]

If I use Flagstones of Trokair to search up a Ravnica-block dual like Hallowed Fountain, do I have the option of getting the Fountain into play untapped?

Flagstones of Trokair
Legendary Land
Tap: Add White to your mana pool.
When Flagstones of Trokair is put into a graveyard from play, you may search your library for a Plains card and put it into play tapped. If you do, shuffle your library.

Hallowed Fountain
Land — Plains Island
As Hallowed Fountain comes into play, you may pay 2 life. If you don't, Hallowed Fountain comes into play tapped.


It's my understanding that no:
1. It comes into play as normal, except that Flagstones' ability overwrites "normal" with "CIPT"
2. and I may pay 2 life, and if I don't, it comes into play tapped.

So if I understand this correctly, I COULD pay the 2 life if I wanted (say for Pulse of the Forge) but even if I do, the land comes into play tapped. Right?

And it would be different if the Fountain were worded as, "Hallowed Fountain comes int play tapped. As Hallowed Fountain comes into play, you may pay 2 life. If you do, untap it." Right?

You are correct.  Hallowed Fountain's ability allows you to pay 2 life to ignore its own "comes into play tapped" clause.  This doesn't do anything about any other effects which may cause the land to come into play tapped.
