Might be worth getting a set of the avid levers that can be adjusted? Not tried them but it sounds like you’d be able to tweak them to work a bit better possibly.
Plan is going 1x9 anyways, which means I can ditch these STIs and will get a set of proper, long arm V-brakes and levers for them. But this is a long term project, maybe next year sometime. :)
In the meanwhile I'll probably put together a dirt cheap fixie skidder just for the sake of it.
