if you wanted to go the mad route of defining legit sending ip's via their 
helo is

"v=spf1 include:%{h4r}.smtp.example.com -all"

That doesn't validate the HELO name.

and ensure the spf for each xx.smtp.example.com is
"v=spf1 A -all"

You are confusing the HELO and MAIL FROM identities.

no i'm not this is the second identically functional equivalent to your HELO 
within spf syntax

show me one possible exception that would pass this rule and fail yours {or 
vice versa}

if you can't then admit the fact the two i have sent {though the latter}
v=spf1 a:{h4r}.smtp.example.com -all

is much more compact and simple to achieve identical results
