I agree. The Pro S is actually preferable to me. I never use the detachable feature on my standard Professional. I have a 7mm Rem Mag barrel that will probably be used on this stock as well. So the bipod stud may come in handy at some point.But will be priceless when you bolt a .300 barrel that does not have a barrel-band front swivel mount and on which you may want to occasionally use a bipod
Additionally, I like the Pro S. The non detachable firing group/magazine is impossible to loose accidentally...
PS: this is when the 18 oz. kickstop may make sense
As for the kickstop, I may put a 12oz stop in it to bring my 458 weight up to 9lbs, but if I use a scope, I doubt I will want the increased weight.
