We have no air conditioning (it's extremely rare to have it in Germany outside of business space and cars), live under the roof (with high ceilings though) and have very effective floor heating. So you do notice seasonal changes quite a bit, necks get spikey in winter as the fretends stick out etc. In Germany, summer tends to be rainy and humid, winters dry and cold.
I distrusted that friggin Fender ballend tool from day one, just didn't look to me like you could get real torque with it. And sure enough you didn't.
I don't have issues with adjusting "from behind" (no, Mark, don't say anything now!) and see the advantages in headstock stability, but Musicman should be eternally thanked for that wheel idea!
I hasten to add that on my 20 year+ basses, I adjust the neck much more seldom. As wood grows older it seems to lose the capability of losing and gaining humidity to the extent of younger, fresher wood. Generally, after 10 years or so, my basses tend to settle in.
