"Also, i think judo/b.j.j would be a more effective combination, because judo throws actually throw someone..."
This statement sounds like your saying that aikido throws DON'T actually work.
You should train with better aikidoists.
Spend some time with the right folks and you will see that good ukemi is NEEDED to save your bacon, and when they want you to fall, you will.
True, there is a LOT of hippy, reactive BS aikido out there, with LOTS of people giving ukemi and ready to fly at the slightest hint of technical bafoonery, er,... I mean, um, technique.
But there are also folks who train proactively, with movement directly to the center, and a concept of good atemi lines and how to actually hit, and the training then becomes about technical workmanship, not just bludgeoning each other.
I have to say, I get a little tired of viewing all of the "aikido sucks" stuff in here, mostly spouted by folks who seemingly have little or no training in aikido, just observations. This attitude, of course, is a reaction to the plethora of folks Youtubing their crappy technique.
I am NOT saying that I myself grasp the great secrets of the art or am good at any of it. I am a student with only a decade and a half behind me, but I have felt and seen people DO real technique, just as hard throwing as I got in Judo years ago, and have been hit as hard as in my Karate training, as limited as it was.
I will get on in here in a day or so and give my BS about what I think the training is, if folks somehow think it is important, but for god's sake stop bashing the art wholesale. If you are gonna bash it, be specific at least, and show some shred of knowledge as to WHY aikido folks have magic pants, funky gripping-the-wrists attacks, and oddball, not real striking methods!
I am not trying to start another fight in here, just givning some feedback.
