I have an A-5 and like to play woodsball. I've been wondering if the stock is really worth the investment of the 60+ dollars.

Yes:  Stocks not only giver your marker a Sim feel, the ladies love it, and it supports and steadies your marker when you play.  If I've intrested you, your gonna love this.  (Deep Breath.  Drinks water.)  Okay, first of all what postion do you play?  Front Lines?  Mid?  Back (basically a sniper)?  Front lines=  collapsable stocks (like the BT Car Stock), foldable stocks (like a Voodo), stock stocks (like the nasy lapco one on the website), and SAW stocks (like the M98 249 SAW stock).  You want to be small and fast, and have the ability to adapt to each situation by chaning the appearence of your marker if possible, like giving it a smaller profile, which enables you to be fast, and furious in close combat situations.  For example, peeking through windows or looking around trees might mean you should collapse the stock, while running or slowly moving in long distance fire means keep the stock up.  Mid Lines=  A SAW stock (see above), or a collapsible stock (like a Tapco T6).  Mid players switch roles, but they never often hit the front lines like the front linesman do.  When it comes to a Mid Player, support is all that he really needs.  I use a SAW stock, even though I play front (I tuck it under my arm when I peek into windows and stuff depending on the situation), but when I play Mid, this thing rocks.  Back Linesman or Sniper=  any stock that doesn't collapse (unless you really want one, then again it doesn't matter, but still) like a an F/X Commando Stock.  Snipers= no movement, or cover positions, and a sturdy stock equals better aim and more control.  If you play speedball however, then don't get one.  But if you play nothing but woodsball, then go ahead and treat yourself to a stock.  I got one and I love it.  If you want other suggestions, mail me (private message).  I got the cure for your disease, because there are other options (like N2 and Co2 butt plates) for example that require no stock, but I'd personnaly get one.
