Alright, I've been a little hard on my new bass. A while back I cracked my bridge, now I broke my d string. I've ordered a new bridge and will be buying strings soon. I will have a luthier fit the bridge. With so many choices and the high prices of bass strings I'd like to make the right choice. I play mostly Arco, maybe a little pizz here and there, but mostly classical. My bass is a cheap Chinese 4/4 with a thick spruce top. I like what I've been reading about the spirocores, but would they be appropriate in this situation? What gauge should I try, maybe mittels? I don't think I'll have a problem with bowing, I've been bowing instruments for years. I have been impressed with the Thomastik Infeld strings on my other instruments and am inclined to use them on the bass as well. Any help is appreciated. If I need to supply more information I will be glad to.
