Interesting perspectives. The other week I ended up purchasing the Mighty-Lift D95004 that I show in my posts above (maybe same as NAPA?). I purchased these because I felt the Wilkenson style (Detomoso) struts felt pretty stiff. However, I admit the Detomaso ones are more stiff with the hood open and real soft in the spot to latch the hood when shut (I thought maybe that was just due to hood leverage, but maybe not). I asked Wilkenson about those Detomaso struts about a year ago, and he said he has never had any problem with those Detomaso struts damaging any hood. So, I may end up leaving the Detomaso on the car in the end, now that I see these posts. Looking at both struts however, the Detomaso are larger diameter though, so I was assuming stronger.
In regards to car with wing or not, I don't think it should make any difference, since the same strut pressure is on the hood when you are closing the hood with our without wing (without wing you just need more hand pressure on the hood). Wilkinson only sells the one same set strength Detomaso for wing or no wing.
Maybe someday someone will measure some of these strut options on a scale and report back the extended and contracted pressures. If I had mine out of the car I could measure them with my 4 post lift to contract them and a bathroom scale.
