I've run a 30T 11-34 for about a year now. My widgit is stuffed the guides are all bent and so is the ring, no noticable wear on the ring though. but I am now switching to a MRP G2 SL mini with a 32T renthal ring (bash guard recommended in my locals), before the bent widgit ring causes me more problems. I have also heard of single speeders bending the widgit ring when putting the power down.
Chain suck in a muddy conditions is common and if its long grass or leafy plus mud, the grass and leaves pack inside the guide resulting in dropping the chain. From the initial installation I needed to bend the guides out a bit to stop chain rub.
Its a shame really, cause I like the widgit for its simplicity in design and function, but it simply still needs a bit of design tweaking.
This ring is simply not up to taking the hits of some aggressive trail/AM riding. I see they now offer a bash guard as well, which may help to prolong the life preventing the damage that I have inflected on both the chainring and the guides.
Even thought its a bit exy.. I would recommend the widgit if you want to test out if 1x? is for you or not, due to simplicity and set & forget setup.
I also have a spare set of cranks with a tripple ring ready to go in my garage, just incase for those marathon events, but have never needed to use it yet.
On average the 30T ring will resulting about 5-10 extra cadence for the same speed as a 32T ring.
