Better Bass Scale for M&H A

[Farrell]

Hi Roger, thanks. Why don't we see German loops more often? Is it because the common type are easier/faster/cheaper to produce? Do the German double loops have any track record of significant failure?

I can easily see where the common loop would make the back length very stiff, but would that necessarily restrict bass bridge movement - the common type should still pivot on the hitch pin - how does a more flexible rear length free up the bridge?
