I'd like to try EL-OS or just EL. I've owned and ridden (briefly) both a 61cm MAX and a 65cm MAX bike, both made my Marinoni. I didn't find them to be harsh, and this was before my discovery of Vittoria Open Corsa tires. They were certainly responsive and firm in relaying pavement irregularities (and there are tons here in Seattle's immediate neighborhoods), but really flew when you accelerated. Reminded me of my 2015/6 Trek Emonda ALR (aluminum) frame/bike. Slingshot-esque.
