Hey Greg - I have the 210, but have a friend with the 230. we have 750's plumbed in the rear compartments & run about 900 lbs in the nose (weighted as 60% rear/40% front with stock ballast in the belly). You might add a bag in the floor in walk thru section, but we have found it isn't necessary if weighted 60/40 back to front. Good luck and let us know if that works! PS we are using 400 lbs of lead weight in nose + a fat sac. (One of those integrated bow sacs should be perfect with a little lead!)
