They are brilliant birds to fly,but a different kettle of fish to a Harris mate! I miss mine like crazy! They're not half as forgiving as a Harris either and nowhere near as hardy. If you want to hunt pheasant DON'T buy a spar,yes they have guts,but like someone else has said ,it's gonna give your hawk a pasting and you could end up having to try and imp a whole tail pretty quickly.

That's an old thread/diary that I did on mine. Good luck with whatever you decide to do,they're great fun but do your homework first mat
