Yes i have had both, had a B73 on my Electra and the top spec fully sprung Lepper on my Felt, Both nice and comfy, the Lepper was very heavy but both very comfy, The lepper had more springs so got really squeeky after a while so you have to lube the springs and mating metal surfaces often to avoid goin crazy but overall i was happy with either seat although the Brooks is just that bit better quality wise!
