The hop up and the new inner barrel has made my gun go from a 5 inch grouping at 16 ft, to a 7 inch grouping at 100 ft. Also, the biggest benifit to having an adjustable hop up over the fixed is you have more ammo choice.

As for other KM inner barrels fitting, its possible, but you'll have to find one that has the fixed hop up on it. Generally AEG barrels are the after market part of choice for upgrading with and always easier to find. An AEG barrel will have a slot cut at the top for an AEG rubber to work with it. Where as the fixed hop up barrel won't have this, it will be solid instead with just that little plastic nub. Also, next time you have a look at your hop up, look inside, and you'll see its like a BB, its round. The hop up from the PDI is flat straight across the top of the barrel. So you get an even spin on the bb every time, verses it catching the fixed just slightly off and getting a side spin to it.

I'd still highly recommend the PDI unit personaly, but thats your choice too.
