Four winds monk kirin aspect

[Nephril]

ok so my question is i have equipped my monk of the four winds with a slow fall ring he is at level 17 and taken the kir rin aspect. now the aspect states
He gains a fly speed equal to his land speed, but he must end each turn on the ground. If the monk does not land by the end of his turn, he falls from whatever height he has attained.
and feather fall states
Feather fall instantly changes the rate at which the targets fall to a mere 60 feet per round

my question is if i choose to attack and fly about on my turn and end my turn still flying how far will i fall before my next turn starts do i get to move the full 60 feet down even if i have taken all my movement and other actions for the turn.

i see a few issues with this. i am limited to movement in a given round. but does the act exist outside of my movement for the round.
i can see this being used i charge up kick some but then slow fall the 60 feet down to my healer lol. im really fine with it either way just wantign some clarification and since my dm is a huge nazi when it comes to gaming please if you have one post the relevant ruling thanks.

If you have a ring of feather fall equipped you fall only at a rate of 60' per round. If you fly and do not end your turn on the ground you immediately begin to fall, however the ring will slow your descent to 60' which would immediately occur at the end of your turn regardless of any movement you've already taken. Falling is forced movement, like being bull rushed or repositioned. It does not count against your normal movement in a round.

thanks guys i was pretty sure just wanted someone else to say it.
any suggestion as to a cheap magic item that could be used to sustain his flight so he need not deal with falling every turn. i was thinking ring of levitate but upon reading i dont want to deal with the penalties to attack.
