Dredge Nozzle Sizes Do You Use?? Info Needed..

[GBE Mandrel Bending]

I have been making Gold dredge nozzles in our business for quite a few years now and we sell them on our website and Ebay.  We make them in 2", 2-1/2", and 3" OD Tube with slip on connections. Plus we give the customer the choice of a classifier or not, welded to the nozzle tip instead of charging extra for a "bolt on" accessory when they should be included. 

We always have made them with 1-1/2" OD tubing either slip on hose or threaded hose to the water pressure line with a reducer to increase the pressure to the nozzle.

Are there any people who use 3.5"  or 4" or even 5" nozzles?  If so, what sized water pressure tube do you run for those?  I am thinking about making a bigger product line for our customers and am all ears in your input.

What would be your best nozzle?  Short and stubby?  with or without side handles?  Different nozzle sizes?  Water inlet tubes?  

I am also thinking about making them out of 316L stainless for the salt water people's.  

Any ideas would be greatly appreciated.
