just up to you,(you might shoot through chrono before making a decision), I have a bow that has about 2 inches of follow,, but it shoots well and has nice cast even tested on the chrono...I have had the bow for 20 years and dont plan on changing it,, when I make a new bow,, I like the follow to be as little as possible,,, Like Badger said you could heat treat but your bow is pretty normal for straight unheated stave,, that being said,, you could always work on it any time, no rush,, just shoot it like it is and if some time in the future you want to tune it up a bit, you can
I have reworked many bows in my time as a bow maker,(even cutting them in half and putting set back to reduce follow), sometime with great results and sometimes not,,but always feel like I learn something
