I'm not sure if I have found the spine. I may have found the most flexible sides because when I bend it and roll it it "jumps" to the flexible sides and when I bend it inbetween the flexible sides it wants to twist to the flexible sides. So I don't know which is the spine but to confuse things more my commercially made Shakespere rod has the guides on the side that wants to twist to the flexible sides.So I think I will try to place the guides on the most flexible of the two sides because I read that the softer side will cast farther and as Panfisher said it seems less likely to break even though I'll be fishing largemouth with a 10 wt. rod. Muskie and Pike are probably as big as I will ever fish unless I catch a Gar. Any input is still welcome I'm still waiting for the thread so I have time to tape the guides and test it out so I'll be back with the results of my tests
