My first ever gun was a Spyder Xtra, with no other mods except new barrel's mine is still rocking and is my back up gun now.
You just need to know how to look after spyders, i spent 3 months studying the "best" way to look after a spyder before i bought mine.
The new range all have stainless hose's fitted so no more leaky microline they used to fit on the old series. The original green xtra was fitted with microline but when i bought my cobalt blue one it came as standard with stainless hose, as all do now.
The shutter is the higher end of the spyder non-electro range. It has a high capability and although the trigger pull is long as stock, it is still capable of good rates of fire like the Xtra. Teams like Brimstone Smoke won lots of comp's runnin on modded xtra's and AMG's and they did very well.
Spyders don't break down often if the right care is taken, and there is nothing that says u cant treat a spyder like an impulse say.
I now own an 2k2 Impulse and the Spyder, and i would count on that if i needed it, more than a tippmann. There is alot of banter going on between tippmann and spyder owners, as they are on the competing rung of the ladder. At the end of the day, spyders have the standard duel bore + foregrip look and the tippmann have that hard wearing military look to them.
Both really good guns, just putting a good word in for the Spyders.... Kingmanites rule he he
