HI Joe
Welcome to the forum
The short answer, leave the rod as it is, the difference is not worth changing anything for, it will cast just fine, go and enjoy the fruits of your labour
The long answer, A few years ago i ran a series of experiments with the PPB/Spine conundrum , we used one blank and re-built it 4 times with the rings moving 90 degrees each time, The first was on the inside of the PPB.
There was very little difference in the action of a Carbon rod, which is why the big rod builders all whip the rods for straight and do not bother with the PPB. The rod tracks true with each position as long as the section all align, if you have the rings in different planes on different sections the rod is very slightly prone to twisting, but again its not much. It sounds like you have all the sections aligned so this won't be an issue.
Our findings were:
With the rings on the inside of the PPB the rod has the best feel and with the rings on the outside of the PPB the rod has the most power, but again its very slight differences and you would only notice when testing them side by side or by doing the same set of tests each in a very critical way. With the rings at 90 degrees to the PPB on either side it felt exactly the same and was still the same to cast as the other two positions, the only change was the feel, but again you would only notice if you were particularly anal and had something to compare it to directly
A lot of fuss and hassle for not much information
With Cane it is noticeable when you whip off the PPB and the same for some of the softer glass rods, but with Modern Fast glass or Carbon blanks i tend to whip for straight these days (although i have also found 8/10 times straight is the PPB anyway) And the rods are always spot on
So i'd take your rod and fish it
it will be absolutley fine
, if you do feel that it does not track true then you could look at rebuilding it, but i very much doubt you will find anything wrong with what you have done.
have fun and let us know how you get on
Cheers
