I run my Thompson without the remote – still way quicker than getting off, wrestling with a q/r clamp, adjusting saddle, trying to get it straight again, etc.
Cable remote is also just another thing to try and keep working through the winter.
Got a reverb on another bike (obviously with the remote still) – the ability to tweak saddle height without removing hands from the bars is nice but something I rarely do (for me anyway!) – saddle ends up fully down, fully up or at ‘woods height’.
So, extra benefit from having a remote seems to be relatively small compared with having the dropper in the first place.
