What Strings would you Recommend?

I can get my racquet strung with about any string, It can also be cross-hybrid strung. When it is strung with 2 different types of string. And what tension should they be strung at, I am a high intermediate/ low advanced player, with a powerful swing. Any recomendations would be helpful. Also can you get any design on your strings? or do you have to get the logo. Like if it's getting strung at a tennis store, can you take them your own stencil, and have them put it on your strings?
