I think the lopsided B17 CS pictured above is officially retired. I think maybe I hadn't realized how it had gradually become more and more uncomfy. I may try the soaking and tennis ball trick since it's pretty well finished anyway.
I bartered for another near-new Swift a while back and decided to try it out on the LHT. I think I lucked out and got the position 98% perfect on the first try. The longest ride has been 20 miles but it's been working out well for the last few weeks.
