I forgot to acknowledge Paul4be's suggestion of an Alecto - that certainly should tick all the boxes (though I am a bit adicted to British or German engineering)

Apart from my slight conern about the power of the HW40, I also find getting a good grip with the weight of the scope a bit tricky - it just feels as if it wants to slip forwards out of my hand so I hold it a bit tighter than I really want to. Maybe the Alecto's grip would help in that regard?

As I siad, I will persist with the HW40 for the meantime and if it doesn't work out, look to an Alecto before the Falcon. Anyone out there using an Alecto for HFT?
