I 100% would not bother chasing a Lemond if you already have the KKRM. The Kurt with the heavy flywheel was one of the best trainers prior to the smart revolution and is much much much quieter than the Lemond. I’ve done literally thousands of standing and rolling full gas efforts on my KKRM. I retired it to upgrade to a 2nd gen Kickr and would 100% recommend one of those too. The kickr has a toothed belt (not sure if they still do) which eliminates slippage that other trainers may have with their v belt on high resistance efforts, plus the Kickr had the highest resistance at the time IIRC
