Long gone are the days when we looped our remotes to keep liquid CO2 out of the valve.
It is far easier to switch shooting hands with no remote line getting in your way.
The line gets caught on every piece of brush... especially if you are trying to be quiet.
The gas-through stock might look pretty, but dosnt it serve the same function as a bottle with a no-slip cover on?
If it's a weight issue, why buy after market flair that adds nothing to preformance but adds weight to the marker?
It really comes down to style & individual preference. I think some people are just more comfortable with a marker that doesn't have a big 'ole tank hanging off its bottom. Iv'e noticed that some players who have alot of hands-on experience with real firearms seem to like the more realistic feel a remote can provide. They are used to holding guns in a particular manner, and tanks just get in their way. There is more to a markers comfort than just weight - its how it feels in your hand, how it balances when carried, how it hangs on a sling, etc.
Hence the reason I use a remote.
