I wish there was a way to utilize the relatively large number of SPF records

Yeah. Too bad that among SPF's many flaws is that it completely
confuses the HELO domain and the MAIL FROM domain
No it does not. It checks each independently. See my previous post to
your question.
(and on a bad day,
the domains in From:, Sender:, Resent-From:, and Resent-Sender:.)
SPF never does that, please do not confuse PRA with SPF.
It seemed to me at one point that there was some promise that it
would be possible to write an SPF record which applied only to HELO
or only to PRA or only to the return path.
SPF 2.0 was supposed to let you specify which contexts each record is
supposed to apply to, but I agree that it'll never get any traction.
SPF 2.0 won't, because its tied to PRA. That does not preclude SPF 3.0
using the syntax of proposed SPF2.0, which would superscede SPF1 and
really be the second generation of SPF1 (because SPF2.0 was *not* second
generation of SPF, it was hijacking to a completely different usage and
meaning (PRA))
