For me, using the original One's and Fusion 3's I'd have sealant still sloshing around after almost a year so yes I'd say that the thinner sidewalls are a contributing factor here but with the performance I'm experiencing with these new Pro One's I'll gladly take the time to top them off every so often.
For those interested in tubeless tires, I just received a set of 25mm Pro One's from Merlin Cycles that were $86.00 for the pair delivered and it took 8 days to get them. Not to bad when you consider *one* of these tires will set you back the same price here in the US. Actual weights were 258g and 259g and they are much taller on the bike than the 23's but have the same 27mm width inflated. Also noticed they changed the size of the font for the lettering, got much smaller.
Nah, it still was a fun ride! In fact, I met a new ride mate out of it; while I was pulled over working on it, one of the two drivers who stopped to offer aid was driving a city recycling truck, the same guy who works my street, and whom I now know is a fellow cyclist! We plan to ride together soon, so that was cool.
But yeah, you caught the point of my post exactly: there seems to be dramatic difference between the sealant "retention" abilities of the Schwalbe One (the original; hereafter, O1) and the new Microskin cased One models (Pro One, S-One).
I did use the minimum recommended 20ml, but may bump to 30ml when I set up new tires next time. I'm guessing having a layer of polymerized sealant laid down now will have some preventative effect against air loss, so on the repair refill here, I'll probably just put 20ml back.
As far as tradeoffs go, I was very happy with One performance, and honestly do not notice a lot of difference between Pro One and O1. I'd be particularly interested in and would consider using an S-One variant based on O1's "true tubeless" construction, since this bike is my all-season runner, and doesn't have the typical seasonal downtime which is the service interval prompt for most of my other bikes, so extended sealant retention would be nice, even at the expense od a bit of added weight. Maybe.
