I'm more of the one diety is all dieties kinda guy, and all dieties are guru yoga. My practice routine is guru yoga first and main practice, if I only do one session a day it will be guru yoga, after that my main annutaratantra sadhana practice for the second session, and dharmapala practices as last practice of the day so if I can get in 3 sessions a day I consider that a good day. Other than that I have my auxillary practices, other sadhanas, prayers, offerings, etc. Green Tara and Guru Rinpoche on certain days of the month, medicine Buddha on medicine Buddha day, sur usually twice a week. I'm very happy with my practices and will probably stick with my main sadhana for my whole life, haven't received any more empowerments in years but there a couple coming up I will try to receive. Would like to get into dzogchen eventually. The first few years I was pretty eclectic, this practice that practice, but after I settled into a definite routine and arranged my main practices and whittled down the stack to something very manageable and stuck with it then everything just came together, it made a huge difference in the quality of my practice I think, and everything was comprehensible and manageable, it was like the jigsaw puzzle scattered all over the floor was finally put together and hanging on the wall. There are soooooo many practices, I'm very obsessive about getting a complete picture regarding anything, if I'm into an author I have to have all his books, if I'm into a band I have to have all their records, I would spend hours in a record store because I would have to look through everything to make sure there was nothing I was missing. So vajrayana drove me crazy the first few years because I didn't want to miss out on anything but there's just so much to chew on.
Then I put into practice what I knew intellectually, that the essence of the whole shebang was the same, up to dzogchen at least, after that everything fell into place and I settled down. I'm very very happy to have what I consider a well rounded 3 roots practice now and find it very manageable, even while coming home from the 9-5 world, as long as I don't veg out after work or get too distracted, wich happens, but I live a very simple life and want to keep it that way. I think finding one main diety practice really helps a lot if it's one you really feel connected to and gives you tangible results, something you can really feel, bringing it all down from the head to the heart and then sticking with it, keep it simple.

The nonexistence of the transcendence of suffering
is what the protector of the world has taught as the transcendence
of suffering.
Knots tied on space
are untied by space itself.
May I never be seperated from perfect masters in all lives,
and delightfully experiencing the magnificent dharma,
completing all qualities of the stages of the paths
may I quickly attain the state of Vajradhara
