Free: Contests & Raffles.
I think one you get used to the .010 you will like them. I'm in the process of switching from .019 to .010, it was tough at first but the more I shoot them the better I like them.
.019 is the way to go! .029 is a little to big on targets 40+ for me and .010 is hard as heck to see and the .019's pick up more light. I shoot to 100 yard in practice. .019 is just right for me.
I have a wrapped SDP with .019 pins. If I were to buy another one I'd get the top four in .019 and the bottom 3 in .010. If two different pin sizes is not an option for you I'd get the .010 for all. Sometimes I feel that the 19's are too bright. In full sunlight I like to wrap the wrap with some black tape to get rid of the "pin halo" effect.
