XB8-14 comes standard with LONG 3 stripes so called progressive springs the XB9-13 in second shipment came with MEDIUM length 3 stripes ? so called progressive springs. So yes there is a difference in spring length and so number of coils. But how springs work wether or not they are progressive or linear is a whole different story...........................

Springs do get worn out after expensive use, maybe you're comparing a new spring with an older spring?
They are the same part number. These are both 3 stripe front springs. Same length
Pictured below are the new 3 stripe xb8 springs on the left and some I purchased a few months ago on the right. You can see the stripe etchings on the top are different and the coil count has changed quite a bit
Here you can see the wire gauge has changed as well.
New 3 stripe xb8
Old 3 stripe xb9
I like the feel of the new strings much better. I always felt the jump from 2 stripe to 3 stripe was a big change before. But now it is not so large
