May I ask: What caused you to seek out exotic forms of prayer? What is it that you're looking for?
If you are looking for methods of Christian prayer within the Catholic tradition, there are existing "schools" if you will, within the Catholic tradition.
One is the "Spiritual Exercises of St. Ignatius Loyola". For more on these, see this: http://www.newadvent.org/cathen/14224b.htm
I know that (at least in the pre-V2 days) this method was used by all of the Jesuits - in fact, they were required to practice it daily.
I can't speak of its efficacy, however, (never having been RC, just grown up around them). I would advise you probably not to attempt such a sophisticated method of prayer without a spiritual advisor. Since this method is a Jesuit prayer, it's possible that they might instruct you in this prayer.
Or, you could try something much simpler and practice what Serge (a contributor to this board) describes as "mass-and-office Catholicism." It's the daily morning and evening prayers of which variants are said by many RCs, Episcopalians, and Orthodox, both laity and clergy. In fact, this should probably form the basis of your prayer life - other methods should probably form an addition to the "office."
To echo what others have said on this board, if you really want to join Orthodoxy because you love Orthodoxy, then I commend you. However, I would not advise you to join simply because you are unhappy in your present church. If you wish to change, do so for positive reasons - not in reaction to others.
I've met some very bitter ex-Episcopalians and Presbyterians who joined the Orthodox Church because they felt that there was no other place for them to go. And they generally take their bitterness with them into their new church. These are not fun people to be around!
So if you're really interested in Orthodoxy, spend a long time investigating it and then judge it on its own merits - not in relation to other traditions. We have some "liberals" in Orthodoxy too...as well as some people that might be called "fundamentalists." What religion doesn't have both extremes?
And we have controversies aplenty - just different ones. So take some time, don't make hasty conclusions, and practice discernment, wherever you go!
