Can I mate a Thudbuster L post to cloud 9 seat

[Jimws]

Has anyone replaced their saddle post with a  Thudbuster L & mated it to a Cloud 9 seat?  If not could you please recommend a different saddle.
TIA

I did, on my 2020 RadMini 4, worked fine.

I have since returned the Thudbuster to the bike I borrowed it from and am using a Suntour SP12 NCX Suspension Seatpost like the one Rad sells, with a 'Cloud-9 Cruiser Select Airflow ES Softtouch Vinyl saddle'. The Suntour seatposts normally ship with a medium spring (for riders of 140-180lbs). but optional lighter or heavier springs can be ordered for lower or higher weights. The Suntour linkage seems to have a little more slop than my Thudbusters, but not annoyingly so when you're sitting on it, and things haven't gotten noticeably worse in 3700+ miles of use. Not sure what size your RadCity uses, but the  27.2 x 400mm Suntour post fit my Mini.
