It depends on you. If your someone who has a huge social life, then get the phone. if you have friends, but not a lot, like me, and if your willing to spend over $30 a time when you go, get the paintball gun. i would go for the paintball gun because you don't pay monthly and it doesn't cause cancer.
Only the o-rings.
No, you should use only paintball specific of air tool lubricant.
No, you should only run the G4 on HPA.
Only at certain paintball fields.
Their are really only two options... You can go paint-balling with her or you can choose not too. If you really don't want to you could suggest an alternative activity or if you just don't want to go paint-balling in February you should suggest that you go at a different time of year for her birthday.
Absolutely, actually you should only eat potatoes on your birthday.
No, only guns that are designed for propane should use it.
Only if you own the property or have the owners permission.
There is none, only use pellets designed specifically for paintball.
You have to go to a licensed field and rent equipment. You MUST have a paintball specific mask to play. No welding helmets, riot helmets, sunglasses, air soft goggles, ski goggles, ballistic goggles, Only paintball specific masks. Other then that, many people just play in jeans and a tshirt.
Paintball gear is what keeps you safe in paintball. The mask is the only truly crucial piece you need to play paintball (meaning you can walk onto a field without a gun, or tank or paint).
Definitely a tank before a hopper. If you go on Zephyr Paintball they have a 20 oz C02 tank for only 14 dollars and a proto primo hopper for also 14 dollars.
