The result showed that the shorter amplicons must have clustered preferentially. Really preferentially.

To me this has always suggested there must be some sort of competition for clustering that favors shorter amplicons.
Impressive; I was under the impression that inserts much over 800bp simply would not bridge-amplify. Maybe we should try that approach! Anyway, rather than shorter molecules vastly out-competing longer molecules at all lengths, that could be a more of a case where the rates are fairly similar up to a point (1kbp?) after which longer molecules start failing to form clusters at all (even if there were no short molecules present). I'm just guessing, though.
