Spyder Compact 2000 D/L with home-made DELRIN bolt (I'm a home machinist), Shutter reg. and mini-x grip on a drop forward, total Freak! system w/ aluminum back. All this is driven by the ideal gas, constant pressure CO2. (regulated down to apprx. 700-750 LBS. for liquid removal).

This coil does a great job of passing gas. The setup comes with a bottom line adaptor and a quick release at one end (ASA, can be used in vertical position in place of expansion chamber) . It has a tank adaptor with valve at the other end.
COILS in general;
1. No liquid transfer/ positive liquid transfer. Because you are carrying your tank on your back it is vertical and will deliver only gas or liquid CO2. If mounted for gas delivery, even if some liquid did splash up into the coil when you took that 10 foot slide into the bunker, the distance through the coil is great enough that those liquid droplets would convert (boil off, ask your favorite chemist) completely to gas before entering your gun. If mounted for liquid delivery because you drive a Tippman A-5 or you simply want to put out a fire, you can mount your tank upside down to guarantee a liquid supply to the gun. Just remember that liquid is much denser and heaver than gas and will require a considerable shoot-down to release the pressure when you want to disconnect the liquid CO2 from your A-5. Liquid CO2 also absorbs a tremendous amount of heat when it escapes into atmospheric pressure. This means it sucks the livin' heat out of everything around it including your skin and can cause near-instant freezer burns. Be very careful with the liquid stuff!
2. Great anti-theft device. Tethers you to the gun and keeps you from wandering off and leaving the gun unattended.
3. Transfers weight. By carrying my 20oz tank on my back instead of on the gun I can cut my gun's overall weight in half.
4. Flexible. The coil passes well through a pack belt so the pull of the coil is from the front and center of me instead of from the side. How about through a loose jacket sleeve?
MICRO-coil design advantages:
1. No excess gas volume. The coil hose is of small enough diameter that there is not a great volume of gas stored in it. This means you won't have to take as many blank shots to empty it like you would with a large diameter hose or a multi-stage expansion chamber.
2. No recharge lag. The passage is large enough so that there is none.
3. Takes up less space in your finely organized carry case. (cardboard box)
1. It seems more prone to damage due to its diminutive size and thin-but-tough material. The micro-line construction seems a little less sturdy than its thicker brothers in this category.
2. By requiring less space, you'll now need to invest in a smaller field box (we don't want things rattling around do we?).
1. Easy field repair. Sometimes I feel nervous that the micro-line architecture might blow under pressure but it hasn't. Instead, amazingly, it has proven itself tougher than it appears many times. If it ever were to blow, one could just cut it at the rupture, trim the new end and insert it back into the terminal for a quick and easy field repair.
2. Very light weight and compact coil.
3. Get a slide valve on/off. With any remote coil I recommend one to be able to release the coil so you can set the gun down. Its no fun doing back flips with your yo-yo marker smacking you in the head or elsewhere.
4. This coil has worked well for me.
