Mac,
So many things to consider here and the biggest considerations are normally directed to the business formula which you asked be tossed out the window. So are we to also assume budget doesnīt matter? If so, then I really donīt understand where you going with this exercise.
My opinion on soils, is that sandy loam is good but it will depend on the infiltration and perc rates of the sandy loam. Researchers say that the best or ideal growing medium is a well drained soil with above six inch infiltration and perc rates. (USGA Spec for putting greens) Most sandy loams classified soils will be less than that. Which makes me believe the ideal soil would be a sandy soil. But it doesnīt stop there, is the sand angular or round in nature or both, angular sand will compact more with time and initial infiltration and perc rates will drop with compaction from machinery and play. You also have to factor in the water source especially in relation to the quality of the water. Obviously a high salt content will be detrimental if not leathal. High Ph water sources seem to be associated with having a high carbonate content and lead to the formation of Calcium Carbonate in the soil and blocks the pore space in the soil thus decreasing the infiltration and perc rates.
In relation to climates it depends what flips your switch in relation to grasses. Do you prefer a tight Bermuda lie, taking a divot out of a bent fairway that could pass for a green, or are you seeking fast and firm, more often associated or favoring a fescue blend stand or bermuda in a warm season climate. Anyways, if itīs a cool season variety in relation to the climate you seek, I would take a more of a micro climate enviroment similar to San Diego over a climate in regards to Nebraska, which has more extremes on both ends of the temperature guage. Another factor to consider is that a dry climate would be favorable to a humid climate.
So that covers two important factors, there are several more but most would be associated with B&B. Budget and buisness plan!
