Get one custom for you. I'f you're going to do that much rod, at least have it fitted. I know Saltheart will do those and I think M&Ds does a few Arras too....
I don't think there is a factory 10.5 rod. I have a 1205 and am considering a 1204 (after re-employment

) but then I think the next size is a 132x . for the 1286 you'll need to go custom anyway (I'm pretty sure)
