ANSWER:

Yes.  The rule eliminates U and V throw strings.

The rule change is Change to RULE 1-SECTION 19: "Any additional strings or laces (e.g., shooting strings) must be located within 4" of top of the crosse. No more than one sidewall string on each side is allowed. No crosse may have any tape affixed to the plastic. This does not include the crosse of a goalkeeper."
