Nice Mods Mr Tumble, the spring can be a pain in the rear though can't it?
The trouble is were we have the spring fitted you need more effort to operate it, I think if it was lower and fitted with a weaker spring, it will work so much better.
This week-end I'm lowering my wire (like yours) and lowering the spring, I also have a spare pole end, so might just fit it in like yours to make it permanent.
