I'm sorry to rehash a subject that has been discussed at length in the past but I'm hoping to get some newer information. I have a Landpride STB1596 FEL plow with factory installed crossover relief valve. I adjust the angle with a W&R Long 3rd function valve which, without the ability to feather the hydraulic flow, slams the blade back and forth violently. This has been a common complaint here with a great variety of solutions. There are so many types of FEL plows out there that there appears to be no single solution that will work for all.
The cheapest answer seems to be a fixed bi directional flow restrictor but what flow rate is appropriate for my setup? Adjustable rate valves are more expensive but they solve the issue of which fixed rate valve to buy. Several posters recommended this one from Surpluscenter.com.

Then there is the question of where to place the valves so they don't defeat the purpose of the crossover relief valve. Some posters say to put them at the inlet ports of the cylinders (A in the pic) and others say the best place is on the connector hoses (B in the pic). None of these recommendations apply specifically to the STB1596 plow however.
I'm no expert but it seems to me the best option is "B". Since the above valves restrict the flow in only one direction, they won't restrict any return flow. Option "A" might work as well as long as they are not bi-directional but the valves would be more difficult to install.
Any comments would be welcome.
