@Dirt I live next to @Mrs_MS.
@horton came up with the concept, we collaborated to get the first version dialed in. For the record the deal had no restrictions regarding @thager, the deal was I have to charge @ms double on everything and "bump" his fin regularly. Check.
@Mattp is correct 20 adjustments per inch. We've tested at 32 and 40 as well. 20 seemed the smallest before you had to make 2 adjustments to tell the difference.
I believe it was a conversation with @SkiJay that was the start of adding the spring.
@Nam1975 I can confidently say this is a beneficial product for all line lengths. If you measure your boot placement when you mount it you will know exactly where you are at all times, each move is .05 inches.
Thanks for the support everyone
