I got myself an s-150 crs in November. Unfortunately have only managed a half dozen rides on it so far, so still early days. I agree it is a lot of bike but it feels more taught and sprightly than I was expecting that I was pleasantly surprised. It climbs well, and is of course great on the downs. I am coming from an e120 as my main trail bike, and I think it climbs as well as that, and is obviously better on steep downs. E120 is a bit of an antique, but it is still a good trail bike. I was worried I would feel overbiked all the time, but I don’t really feel that. I had a 2010 Spicy for more gravity focussed riding before, and the s-150 is MUCH better on climbs and XC type trails that that.
So, I’d say don’t write off the s-150. T-130 may be a better bet, but for me at 6’3” I really wanted the 29” wheels and don’t regret the bigger s-150 so far, and I’ll be using it at strathpuffer this year.
