Curtis, i too may try the storm with the metz up front. Tho i do worry a bit about the fact that Avon says "We will likely modify our Storm 2 Ultra rear to cope with the load". If they feel they need to do that, then maybe using the current one may not be safe? Not sure whether to wait or not. They say at least till end of the year for the change. One way or another i gotta do something because this 4-7k on a rear is just not cutting it for me.
