Yeh I know alot of the marshals there and also the manager.
My advice to you mate is to save up and buy a mask, then buy a marker, hopper etc and play some walkon days. We have one at paintball alexandria near loch lomond every 3rd sunday of the month. Also the scottishwarriors.co.uk play at delta force alot aswell as paintball alexandria. If you want to play tourny mate its alot of cash and you are still very young to have that kinda money.
Best thing to do is to get into rec ball and develope your skills there then move to onto tourny when you can.
Are you actually in glasgow or just outside?
