options in RC over FB
I am partial to pearl Ilford MG IV.  It is the nicest neutral RC paper that I know of that is also easy to find. The warmtone MG version is nice as well. 
The other option is to consider finding or making a low flow cascade washer, and stick with FB. 
A cascade washer is basically a series of trays that syphon/overflow down to a tray below.  You start out with the print out of the fixer into the lowest tray, to rinse, then can do a hypo clear bath, then back into the washer on the second tray up.  Move the print to the next highest tray after x minutes, and then to the highest tray for the final wash. Water goes into the top tray.  
The highest cascade washer I have found in my readings is four trays high.  I think they were popular around the NE USA due to high water rates; Boston rings a bell.
The other option is to read up on Rowland (Ron) Murray (here aka Photo Engineer) and his work on a fixer known as Superfix. Commercially the Formulary sells a close relative as TF-4. 
I use these for FB paper, without an acid stop bath (frequently changed water only between dev and fix).  I keep track of the pH of the fix, and have to adjust it from time to time due to alkaline carry over from the developer.
These fixes work very quickly, so there is little opportunity for fixer to find it s way deep into the paper fibres, where it is the hell to wash out. Wash times are quite short, and there is no need for a HCA bath.
If you are really concerned about wash water, hunt down a Fuji FRSS10.  It is a resin filter fitted to reservoir that will take residual silver out of wash water. There is a test circuit to let you know when enough ion exchange has been done in the upper reservior, before draining it out the dottom, where then you can recylce the water as fresh wash water. When the filter is saturated, you mail it back to the service depot for silver recovery.
