I'm debating moving up in pedalboard size from a mini (24x7, flat) to either a classic Jr or metro 24. The metro is only slightly larger than my current board, which I like and may be enough. But it got me wondering: Is there an advantage of a flat board over the larger angled board, or visa versa? Im open to either, especially if I can find a deal on one, but what aspects would you all consider between these two types of boards? Help me spend my money!
