Honestly.....
This preset fad is just a fashion thing really.
You hear about the weight saving....An air system, that's bottle and reg, weighs proberbly 4 or 5 ozs more than a preset reg and similar bottle!
Put that into perspective. Strap that lot to a marker, then a halo (with them heavy wrist snapping bateries in it
) then fill the whole lot up with about 180 of them hernia assuring paintballs, and you are looking at saving a very small amount of weight, overall.
In all honesty, in a game, what are the advantages???
Unless you are a weak wristed gimp, then it will make absolutely no difference at all.
The only real advantage of the preset, is the ability to quickly swap it from one marker to another, end of!
It just boils down to the pro's started using them so everyone wants to be a pro and use them as well. Same as any other sport the world over.
Ok rant over...I don't do mornings!
