Ergonomically, the biggest inconvenience of the trough is it's being in the way of the stylus for 1- cleaning it, and 2- visually cueing it to a mid-LP groove (the beginning of a song in the middle of an LP side), which I rarely do.
If you really want to have damping in a pick-up arm (almost mandatory with Decca/London cartridges IMO), the headshell is the most efficient and effective place for it. I've read that the research and development of the original Cransfield Rock was predicated on it's use specifically with the Decca cartridges of the time, and it's design was influenced by the needs endemic to the cartridge. But what is good for Deccas/Londons is also good for other low-compliance cartridges.
As for not being a set & forget record player, sure, it's not like, say, a Rega. But neither is any other high-performance table; think about what owners/users of the Eminent Technology linear-tracking arm have to go through to maintain that arm's performance. In comparison to an ET, the Rock is a breeze!
