so i inherited some markers, ones a mini, 2nd is a piranha, next is a spyder victor...(POS) i need help figuring out the air systems for these guns. the mini came with a crossfire hpa tank, typical 68/4500 that gun is fine, for my other 2 (im pretty sure i know the answer for this post but whatevs) markers (they are for friends to use against me)i need to know if i should go hpa? and spend the extra money, which I dont really have (have a method for plan A) or should i say whatever and get c02 for the both and have money for paint and what not. the reason im saying hpa for the 2 is because where i live its cold and went for like 3/4ths the year so co2 would hardly work. 2nd since co2 has inconstant pressures the guns would suck therefore they would complain and B**CH about how im giving them the **** end if the stick, which makes sense but i dont want to ruin a time at the woods because of that. but to take into account its going to be muddy so it might not even be till summer till we play so co2 could work. idk its confusing.
