RE: Zebra or W.C
If these are your only two choices, then the WC is the better. Another choice is a Berrystring from Wayne Newberry. These custom strings are great, no streatch and very durable. The are made with Ultracam and can be made to your color prefrence. The nice thing about Wayne's strings is they are excellent, just as good or better then WC in my opinion, quality at about half the cost of the WC strings. For a Mathew's string and cable it will cost you about $50.00. Check him out at Berrystrings.com.
