I was quite impressed by the difference that Kojaks made over Marathon Plus on the ICE trike. Much faster rolling, and pleasingly grippy on skog-free tarmac. There seemed to be a sweet spot for comfort that required careful tweaking of pressures to find.
The Duranos on the Baron aren't bad either[1], other than being in the process of dying of old age. Not sure what to replace them with - I'm putting that decision off until my ankle has sufficient stamina to appreciate a fast bike again.
[1] Well, the bike goes quickly and they haven't had a puncture yet, but the bike's new to me (I'd only just got it properly dialed in when I went and injured myself, so I've only done about 350km on it) and I haven't tried any other tyres on it.
