I don't know how shoot vendors are in the UK, but here in the 'states, if you go to any shoot of at least "state championship" size, there will be a half-dozen people selling Pilla lenses who will be delighted for you to try them on and take a take a look at clays in multiple different backgrounds. That is any easy/peasy way to try different lens "colors" for what works for "your" vision. Then, armed with knowledge, you can determine if you want Pillas, or to look for similar colors in other brands of lenses that are less spendy. I agree that everyone's vision can be quite different. Many of my Master Class shooting partners swear by "orange enhancing" lenses. Those do nothing for me, but "green dampening" lenses make a difference for me, shooting in trees/fields most of the time. YMMV.
