Thanks- that is all very informative. And it does sound like the Thinline needs a 280TN rather than the 200TN.

I have a solid Tele with 280TN and 290TLE which needs some expert twiddling and I'm thinking if I send them both in at the same time I could have the 280TN transferred to the Thinline, and then the 200TN could go into the solid and live there with the 290TLE, which could be a better match since that would then be both pickups that have a little less high end (200TN, 290TLE) in the same guitar. OR- I could just get another 280TN for the Thinline.

I got the 200TN after being very impressed at the sound of the 200SN and 200SM on a Strat. But it seems that Teles and Strats may be a little more different than I thought. It's a great thing to always be learning something new.....;-) R
