Sufferfest on TruTrainer Smartload rollers

I turned my TruTrainer rollers “ Smart “ and am looking for feedback from anyone using them with Sufferfest. Power seems to be fairly responsive. I use the readings off my Assioma Duo pedals. Cadence seems to be consistently lower than the target. Cadence has always read consistently from the pedals but before the Smartload conversion I controlled cadence and power. I used the ANT connection as Bluetooth did not seem to connect well with Sufferfest. If anyone is using Smartload rollers with Sufferfest I would be interested to hear about their experience.
