Morning all, yesterday I picked up a new s510 in a rather beautiful thumbhole stock, this came about when I walked into my local fishing/gun shop and I was presented with it without asking, stuart knows me too well haha and knew this one was for me, I was going to buy a hw100 off a friend which caused me some dilema but side by side in the shop there is no comparison in my opinion, yes yes I know side levers bla bla but the weight,feel and frankly the quality feel of this s510 next to a hw100t is a different league, but the hw100 is self regulating I hear you say, frankly a reg deems irrelevan
