Sorry danny, I've not seen that particular 'off main brand' driver advertised in the UK so can't comment specifically, but I've seen others like them - lots of Golf Channel advertising, promising great things, but the result is an average club of average quality which was obviously demonstrated on the TV by a player of above average ability (I've seen a right-handed trick shot golf pro use a left-handed driver to smack the ball 250 yards down the fairway, but I wasn't tempted to buy the left-handed driver...)
By the sounds of it you should in any case stick with the HRG, I'd certainly be happy with a 15 degree club which I could hit 250 yards consistently down the middle!!!!
PS. I once played with a guy who had a driver which looked like a can of beans on the end of a pole, unusual but he could certainly hit it a long way, just too often a long way in the wrong direction...
