May as well use 40mm scope hols. Crush it flat which I think is about the best use for them and see his much surface area they remove. They effectively increase your depth of field as well. You may not see it on 30x or whatever you are using but on a high mag with a shallow depth of field it's noticeable.
If they are so wonderful at cutting down flare why don't they use them on any camera?
They're a supposed anti reflection device so people can't see the reflection off a scope. It's not meant for cutting down flare in a scope although that might be a by product. Drill a 40mm hole in your scope cap and it will probably do the same.
Just how heavy are the s&b shades????
