Bias, Radial Or Both For Street Twin

Does everyone replace their bias front/radial rear with both bias or is there another bias /radial combo besides the Phantoms? Too many tire threads to sift thru to see every combo tried.

 

Thanks. I figured most would go for bias on both ends and not risk running a radial up front since Triumph doesn't recommend it. After a bit of searching for ANY 18" radial, I found that the Spirit ST is about the only choice if you want a matching 17" rear. And it seems those that have tried them, have no complaints. I've owned about 30 different street bikes and none had radials so I had to order a set. Unfortunately, Avons aren't as popular as other brands here in states so it looks like I won't get them until May.
