Alex and Scott,

Thanks for the feedback.

It appears there may be a market for a frame that would handle both 7x17 and 8x20.

It could be the same height as the 24x30cm size, but somewhere between 54cm (21.25") and 60cm (23.6") in length. How much extra wiggle room do you like? The 24cm (9.4") height should be fine for both 7x17 and 8x20. Would 54cm (21.25") be long enough, or would you prefer something a little longer?
