Oros Screw On Strike Indicators

Used these extensively on a recent 10 day trip to the Bighorn river and Frying pan river.Had heard about slippage problem before but did not have any difficulty with the med and large.Did have some problem with the small but solved it by using the washer from a small airlock indicator.It is very hard to adjust the small when hands are wet and cold trying to get a grip. The ideal solution would be the OROs using the new foam airlock biodegradable foam which has a better grip.I suspaect the OROs and Airlock new version will render all the other plastic ,cork and foam indicators obsolete which is good as the all kinked the leader to some extent.
