Thanks for sorting this out Rage. I'll be able to get to Finsbury park, the trains take about an hour and run every 30 mins, so if you could let me know what time you want to be leaving finsbury park then I should be able to get there (although I must confess to not being a morning person).
I'll probably bring my aqualung bag, which is quite large and has a rigid base and back, but if there is an issue with space I can try and squeeze the gear into a rucksack.
Gear wise I'll need tank(s), weights (have to figue out how much) and a weight belt. Although if they rent reels/SMBS etc then getting a couple extra to play with would probably be worthwhile. How many dives do you want to do ?
As for suits I'll bring my 5mm (which should be ok if the water is 21C as reported), but I'll probably bring a shorty to go over just in case. I would love to try out a drysuit, but if we don't have any instructor types with us I don't know if this would be a good idea.
Cheers
Conor
