Mike, I count the revolutions of the cap you have to grab, which is easy as it as 5 or so 'divots' in the top edge.For ages i never even took notice of the thread!Also I hold the spring whilst turning the cap with the other hand.**** they can be tight sometimes!As for leaking :shock: Progressive seem to be afine bunch to me so I reckon they will help ya.
