Hi Micky.
As mentioned, UCAP Sandpit it only a few mins away. Only problem is that if you go there; you'll never want to play anywhere else ?
Best bet is to head down and rent for a couple of games. This will give you an idea of how and where you want to play.
Talk to the guys (and girls) there and get to know the gear and the people. Most of us are a friendly bunch who are more than happy to show off our gear - so you'll probably be able to handle a few guns in the SafeZone and get a feel for what you like.
Looks first, but comfort and useability is a close second (for me anyway).
3 games and you'll be able to get UKARA Registered to buy yourself something suave (assuming your over 18...?)
Don't worry about buying all THE BEST KIT EVER straight away. Start of small, cheap combats and cheap (but good) eyepro/full face - and let your gear evolve with you.
If you try to buy a whole load out straight away you'll likely find you don't want/need/use a lot of what you bought.
Lastly, welcome ?
I'm from Greenhithe - looking to get back into the sport in 2016. So, maybe I'll see you at the Sandpit.
