Hi Darren,
I'm in Cheshunt if that's any help to you although I cant do anything this week.
other than taking you out for the day you are welcome to come round have a cup of tea and play with the kit.
I can show you the set up & let you have a go. my system is a diy van mount i kitted it all out myself. i think kitting it out yourself is the best way some will disagree but if you have built it you know how to fix it should it go wrong.
i wouldn't say i am greatly experienced but i have been going since April and haven't had any complaints. i also went on the bwca course when i first started.
drop me an email
