It is not for me to tell you how to fly your aircraft but it seems that you are happy to restrict the number of airfields you can use.
Most people here seem to say that maintenance costs are the reason for not using grass runways , but how meny of you have had to replace the main bearings on the landing gear that take the for and aft loads ?.
I would lay odds that most of the maintenance costs go on the side strut bearings ( the ones that take the most load in a cross wind landing ).
Comments please.
