Even though there has been has been a shift towards more militaristic markers, speedball markers still are a great option for the game.  Unlike magazine fed markers or woodsball markers in particular, the main advantage of speedball guns is the speed and light weight.

One of the great things about speedball markers is they are incredibly fast.

High pressure air tanks work great on any paintball marker, but are mostly used on tournament style guns.  Covering your hpa tank with a decorative tank cover is a smart way to protect your tank from dings and scratches.  Tank covers are available for CO2 tanks as well but the best selection is found for hpa tanks.  Paintball gun air tank covers come in a large variety of colors, patterns, cool designs and even custom artwork.  This offers tons of options for customizing your paintball marker/tank with matching accessories.

As you get more addicted to paintball, sometimes it becomes tough trying fit it all in.  Keeping your grades up while playing paintball is a hard thing to do.  Especially if you're playing other sports (along with paintball), you need to find time to get your school work done and still be able to play.  You'll have to manage your time wisely while playing paintball during the school year.
