The original poster asked about where he could go to help progress his skills in IP/aiki. Dan's reply is appropriate and true.
no. dan's reply might be true, but not helpful. the OP asked if the local taiji at the YMCA worthwhile to try in helping him learn more on IP/IS. an answer of "highly unlikely" would be suffice, because folks who know both taiji and IP/IS are rare. instead, dan went on his usual spill about IP/IS and martial artists, i.e.
1. most martial artists, including high ranking, don't have much of a clue about IP/IS
2. find the teachers of IP/IS that have students who have demonstrable IP/IS skills
3. only very few teachers out there have the goods and most of them aren't/weren't westerners
personally, i think dan should just cut and paste that to all of his posts to save time.
