Trail springs absolutely remove the odd pedaling sensation that I experienced, but according to Rimpact they also decrease the chain dampers ability to absorb energy from the chain. I'll be honest... I haven't been able to "feel" the difference between the hard springs and soft springs on the trail yet. I'd really like to do a back-to-back day with laps on the stiff springs, soft springs, with a normal chainring, and an Ochain, but I just haven't done it yet. It's been hard for me to parse out what I'm feeling without that sort of back-to-back testing.
