I tried repeatedly to post comments on your blog, but was unable to do so, so here they are. You're welcome to put them on your blog:
Great post, and really good points about Lumpy and other sympos like it. You write well. I particularly liked weighing in when the sword swings too close. I know of no setting that places a greater demand on the skill and judgment of trip leaders than the open ocean. That anyone is willing to teach there is amazing & I have a lot of respect for coaches like Sean Morley who step up to that daunting plate.
Wayne Horodowich (University of Sea Kayaking) has written an excellent article "The Mental Game of Rolling" on paddling.net, and there's also a lovely article entitled "Rolling My Kayak" by Warren Willianson on the USK site. Both are great reading following an unwelcome swim.
