Looking for suggestions for bow ballast replacement (seal failed at factory bag fitting on both bow bags). The fly high W711 (single bag) has 3 ports for drain/fill and vent. How to you connect into this bag since the factory set up has 3 on starboard side and 3 on port side? Interested in other bow setups anyone has tried. I typically run the bow at 40-60% both sides anyway so is it necessary to replace with 500lbs?
