Are you replacing cables as well?

Depends on the string quality, who makes it, off the shelf etc. There are tons of string makers around, I recommned GAS Strings (www.gasbowstrings.com). They are made by Eric Griggs, give him a call or check his web site.

You will need a press to put the string on. The shop "should" do a simple re-tune to synch the cams, put the nock point and peep in. But ASK THEM FIRST make sure its included.

The shop may also make the strings in house, quality here can vary from shop to shop even tech to tech in the same shop, or they may have a 3rd party place they use.
