It seems a lot of teams have had this problem, and some have not. The move to 4-cim drives to replace 6-cim might help mitigate it a bit, but I guess time will tell (or good testing).
Broaching pulleys from SDP-SI or using larger pulleys from Vex and turning down the flanges would allow you to use a slightly larger pulley and reduce the risk of belt breakage.
