I give up too. You keep doing your Aikido and I'll keep cross-training BJJ & Kickboxing & Judo & JKD stuff. But just remember, never rely too much on any one system. Smart martial artists usually cross-train nowadays cause it has been realised that no single martial system is sufficient in the modern age. Total dependence on any 1 system is foolish as it applies to self-defense/fighting, but if 1 system makes you happy, that's all that counts!
