I second the TI and coach route. Even one or 2 60min lessons, especially with video analysis, could be a big help. Also, I'd forget about doing anything more than one lap repeats with good rest after each rep until you can get down to a comfortable 22 or less strokes per SCY length. 30 per SCY length is indicative of a massive balance or technique problem that needs to be addressed via drills. there is no short cut! Swim golf is a good game for this (spl + time = score). You can even do laps taking no more than x strokes and kick to the end if you cant make it.

Another good option is to get a friend with a video camera to film you swim. A coach could do underwater stuff (or you could if you have the equipment) but a lightbulb might go off re: a thousand things just by seeing yourself from above. Things like arm crossover, leg scissor kicks, fishtailing spine, etc., which can each be addressed through drills.

The drill thing can be frustrating b/c we want to be constantly "upping the yardage" to indicate progress, but its the only way to go IMO. That is how the women and young fish-kids that I could bench press 5 times over can effortlessly glide by me in the next lane. Its all about comfort, balance, and technique.

Also, look at it this way: A crap swim means you have nowhere to go but up. Don't ignore it, unless you honestly hate to swim, in which case the du route might be for you. I was a runner/biker w/ no swimming background and it was really fun & satisfying to realize massive gains in this limiter each season.

Good luck!
