Thanks everyone, good to know some tricks to navigate my searches a little better.
Blue...thanks for the carto info. I just know there's so much to know with them, like what will and will not work on passthroughs, etc. Didn't know if there were maybe some of them that just flat out wouldn't work on the ego or not. So far I have some 1.5 and 2.0 dc, and some 2.0 sc on the way to go with my manual pt which is also on the way. Was just wondering basically if any of what I already have would work on the ego or if I have to order more stuff if I choose to get the ego. Still on the fence, I'm still reading through all the links Ms. LS9 was kind enough to provide. But I'm thinking I may just give it a try, what the heck. Now...where's that wheel when I need it.
