Tempted to get one for the next helmet (need to replace in a year), but it is just too expensive imo. Also I typically always have tailbag on me with water, rain layer, etc and it is easy to throw either the tinted or clear visor in it as well.
Next helmet will be a RF-1200 to replace my RF-1100...and I think the transition visor is around $210, vs about $80 (or less on sale) for a tinted to go with the stock clear. If it was only a $20-30 mark up, I'd probably give it a try, but not really at double the price.
