Hey Kim, Gary Daehn here from Wisconsin. KISS Classic number 408, purchased and trained through Tami. Couple of quick questions. I bought my KC just as the BOV was changing and have never dove the "new" model. Is there a significant improvement in WOB? Enough to consider spending almost $900 to change it over??? Since it is basically the same BOV as the Sentinel (at least internally) has there been any thought to changing the risers/QD towers to utilize the larger diameter Sentinel hoses. Would it not make an appreciable WOB difference? Has this already been discussed and rejected? Thanks, Gary
