Spyder e-99 w/ Java 68ci fiber-wrapped tank, Bob Long Torpedo reg w/ 32degrees mini gauge, System-X cradle with on/off, Full Force Delrin bolt and a Halo B
Strengths:
Very Consistent output, comes with thread cover, well constructed and fits all standard cradles. Can come in black carbon fiber instead of gray (just looks a little better in my opinion.) And obviously it makes a great improvement from C02. (as any nitro tank would)
Weaknesses:
As everyone else says the threads are weak, but not as weak as everyone else makes it seem, hasn't effected me too much. I specifically ordered a PMI pure energy tank and this came which TRULY PISSED ME OFF, I was too lazy to send it back. Also mine came with some scratches on the metal and a slightly cracked gauge( but it worked fine). That is all due to the place I ordered it from and the shipment though I suppose.
Conclusion:
Even with the weak(er) threads I have had no leaking problems. This product does its job extremely well. All preset tanks are about the same however so I would necessarily recommend this but I wouldn't not recommend it either. GOOD TANK.
