Yup!!
The re-ball thing wasn't working for us... Don't know why but guns didn't really like them too much... so we turned it into a paint arena instead, it's a small section, perfect for drills and snap shooting etc. not ideal for games larger than 2v's2 but great way to get some training in on the off-season..
Go to AsylumPaintball.co.uk and check picture out in players area section and if you fancy some trigger time give me a ahout on asylum number 01614060276 after 6pm or drop me a pm on here and I'll hook you up.
We've got air compressor to 3000 and can sort paint if you need it.. We do still have the re-balls but really did struggle with them.
We also have a speed ball arena which is good for running and gunning drills and games but it's not sup-air. If we get a few random players who can't get the team down and fancy it then I'll hook up an open night where players can come along and just jump-on or join in. Got some killer kids training regular who could do with being shot up some to keep their heads from growing!!!
