sliding is a VERY difficult skill to translate through writing. i suggest you find a VERY good baller at the field you go to. remember, someone who really IS good, not just someone who THINKS they are good......i suggest you ask one of the refs or field staff members, they should be able to suggest someone who is qualified to teach you the RIGHT way to slide into a bunker.
just to TRY to help you online, here i go. there are TWO ways to slide in paintball. the superman, and the baseball slide. here's an explanation of both.
superman: this slide is meant for tape runners. remember, in a superman slide the entire lenth of your body is exposed, so you can really only use them for bunkers where you can afford to have portions of your body exposed for a second or so. for example, if you superman into a dorito in a tape line. more often than not the paint is going to be coming from the inside of the bunker, so its more important to get past that paint, than to have a small portion of your body exposed to the outside lanes. supermans are also perfect for a vertical laydown like a snake, where none of your body will be exposed during the slide.
how-to: you run as fst as you can...velocity is key to a good slide. right before you slide you want to make sure you are as low as you can get to the ground to make the impact less. a few feet before the bunker (depending on how slick the surface is) you essentially throw all your weight and momentum into a foward slide on the OUTSIDE of your forearms (with your gun up, instead of down....put your palm out, then grasp your gun....that is how you position your gun during the slide). you do NOT try to land on your stomach...that is a way to get hurt. the primary impact of the slide is on your forearms, then on your thighs and knees. then as you get into the bunker, use your forearms to push your weight up onto your knees which will get you into a kneeling position. the key is to get onto your knees with your chest essentially touching your thighs, this way you will be on your knees and be able to snap up or out, but at the same time you will be as low as possible so that you cannot get picked off over the top of the snake/bunker.
baseball: this slide is used for bunkers that you are moving into horizontally or diagonnally. this slide allows you to quickly pop up and shoot your opponents as quickly as possible. this slide is essential for corner runners and 40 bunker runners.
HOW-TO: if you want to know how to baseball slide, just watch any baseball game, that is how you do it. you are sliding on the SIDE of your leg and @ss. with your body at a 45% angle with your legs. the legs slid on depends on whether you are going to a left or right bunker. for this how-to, we will describe it as if you were running to a right corner bunker. momentum is VERY VERY important for a baseball slide. more so even than a superman slide, cause not only do you need to momentum to get your body to slide, but you ALSO need the momentum to get your body into a standing position after you slide. you run to the bunker directly, try to remember to keep your eyes on the keyers so you know where the stream is. a few feet before the bunker (depending on how slick the surface is.) you are going to throw all your momentum into a slide on the side of your left leg and butt, while keeping your body at a 45% ANGLE to your legs. remember to keep your right leg IN the air over your left leg....it is important to keep your right foot off the ground or it will essentially dig into the ground and stop the slide. once you are behind the bunker is when your right foot comes into play. you essentially want to use your right foot/leg as a pole vault pole. you dig your right foot into the ground (cleats are essntiall, track cleats with spikes for astro-turf surfaces) and use the momentums of the slide to vault you up into a standing position which will allow you to quickly put some fire down on opponents, and in the case of a corner runner, will allow you to take advantage of your mirrors overslide by blasting them before they can get back in the bunker. please remember, it will take ALOT of practice before all the elements of a baseball slide come together to perfection. just keep practicing until everything is done in the proper sequence without under or oversliding.
hope this helps guys
