I do have justification for my choice.
whether my justification is relevant to your friend, I have no way of knowing..
if you post your reasons up im sure people can decide if they are relevant
for all I know he may not even need a chaiguide!
thats not the question here, he is asking which one to choose, he is more than capable of deciding if he needs one, he is a very good and experienced rider just trying to choose a new guide.
BTW all chain devices need spacing to fit different chainline/frame set-ups?
in my example I was not refering to the spacing from the frame, I meant the gap between the top plates, I had to put a washer between them to make the gap larger as i had chain rub, the chain hit either side in top or bottom gear
tbh I think your reading too much into this post, its a simple question which guide is the best for the cash. lg1+ or the mini g2, not "do I need a guide at all", "what guide for a pub trip, or "what guide for riding over sheep"
