I have to agree with Brian, where's the fire??? If your that woried about getting used to LiPos then take an educated guess as to which packs might be legal and go for them. I'd be thinking major name, large UK distributor, sealed case, inside the stated sizes .... probalby a better than 90% chance that is all these points are met it'll be on the list!!!
If it's set-up time your concerned about then run cells again this year, simple as that, you won't be the only ones!
Paul and crew give up a huge amount of time purely so that you can have fun at the weekends!!! Have a bit of gratitude for their efforts rather than moaning about how long things take to do, maybe even ask them if you can help in some way!
The links below show they are working on it ....

(£100 a pack .... jeepers!)
These work out about £30 a pack and for most people will be fine
