i have the opposite problem. the longer i practiced the more i wanted to practice with other styles. to me, each style originated from one of the deshi. each deshi had a picture/view of what O Sensei's aikido was. so essentially, each deshi had a piece of a jigsaw puzzle. the more styles i practice with, the more pieces that i have to be able to see a larger picture of O Sensei's aikido. for me, i don't like to just own one piece. i want to see the picture. of course, that's just me. other folks might view thing differently.

Another thing i looked at is that when i practiced with other styles, and if i can do what they do, then i know i have good mind-body control. if i can't, because i am stuck in my "style", then it means to me that i don't have good mind-body control. i got to be able to look at someone doing the technique and able to do it close to what they do. that is good mind-body control.
