Hey Trevor --- glad to hear the atemi is working well for you! I find that it works best when your attackers plant themselves/are heavy/don't react realistically to what you're trying to do --- it definitely gives them incentive to move and thus give you the energy and openings you need to do a technique. Hopefully over time you will no longer feel as frustrated about not knowing a wide variety of techniques --- this will only come with time and more practice. I find that "one beat" techniques like Kokyunage are usually the best for Randori when it comes to buying you both time and space to move around in...we used to do at least one Kokyunage at the end of each night, so if you find a variety of these useful to know for Randori purposes, certainly bring it up with Sensei --- the more requests he gets for teaching/practicing certain techniques, the more inclined he'll be to cover them in class. Another thing that also helps one's Randori is relaxation --- you missed a really good relaxation exercise we did last week that would be really helpful to you --- you should ask Sensei more about it...I find that when I change my frame of mind and relax, it's easier to see openings and I find that I'm not struggling against my attackers' energy so much as blending with it. Hope that helps, and see you on the mats! Jamie
