TE/TC Has anyone tried WP's cone valve AER 48 forks?

i am looking for actual riding feedback/experience on the aer version of WP's cone valve forks. i am considering a set to replace the standard aer 48 forks on my '17 tc250 (which are quite good!).
i have a set of the wp spring cone valve's on my fc350 and absolutely love them, so i'm curious how the air cone valve's compare. if the aer versions are in the ball park of the spring version i would probably opt for the aer version as they are a fair bit lighter and i want to keep the tc as light up front as possible. that said, my experience tells me springs are better than air but the stock aer's are surprisingly good hence the question.

thoughts appreciated, thx.
