The question is are you running out of air?
Can you shoot the paint that you are carrying and last a reasonable amount of time in game?
With in field respawns in long or allday scenarios etc you could stay in longer if you carry a bigger bottle and more paint, but they come with more weight. Are you adding anything to your contribution by carrying more for longer or slowing yourself down by carrying more
I'm running out of air after shooting a full rotor and 3 large pods normally 5minutes before end of game .
Think I'll need to pick my shots more and conserve air more .
I have both a 1litre bottle and a .85 l
I rather take the smaller one due to weight ,I know there's not much diffennce in weight between the two but the smaller one just feels balanced .
Standard for a 3000psi is 0.8 litres / 48ci, your 1 litre is larger than standard for 3000psi, and is approximately the same size as a standard fibre at 1.1 litre / 62 ci so you will only gain with that from the 50% extra of a 4500psi fill, so no good at a 3000psi site
You can get bigger 1.5 litre / 88ci which will give you 50% more capacity then then 1litre when at 3000psi,but with a bulkier bottle
You could just as well spend about £30 and carry a spare aluminium in a backpack and swap over
Tournament paintball has moved over to m500 with hopper and two pods (and next year fully enforcing the 500 limit by specifying the maximum hopper and pod sizes).
If you're running out 5 minutes before the end of a game then I would say to be more efficient with your trigger finger - improve your aim or cut down the bps a little, or look at adjusting your velocity, drop the fps slightly and use less air with every shot, consider a freak set and bore match but that's also more expense if you are just after a bit more efficiency, bore matching will help with that but it's not the only way
(All size comparisons between litres and cubic inches are approximate based on common sizes - so they won't exactly work out if you do a conversion calculation, I've even seen bottles with two contradictory sizes marked on them in the different denominations)
My 1l bottle is one of them green ones in the top right picture .
I've thought about carting my other bottle with me on a remote line and then I could take another 400 balls !
Tho I am a big chap but don't like the thought of making myself even bigger lol .
I'll get a freak kit and barrel back and pick my shots more .
