FE are just the same as all other TDOs apart from 1 thing - THE OWNER
If you can Ignore Kevin at the safety briefings then you will usually be fine, most people experience his grumpy side and this rubs them up the wrong way!
I did last monday at Donington and Kevin wasnt running it, it was meant to be 4 groups but the day was quite quiet so they changed it to 3 normal groups, i have to say it was the best run FE day ive done only 2 red flags all day!
As Dan said, FE can be a pain but if the date fits (and with FE the price is usually right) then there is no real reason not to do the day!
This comes from me who had a real crappy experience with them back in April when they made a right F-up of the groups and i ended up getting taken out by a really slow rider whod been dumped in the fast group and cost me a fraktured rib as i got run over by the guy behind me
Yes other TDOs can be more polite and FE diserve a ripping now and again but i wont stop using them just cuz Mr Healy might be there with his grumpy face and poor attitude - bad track time is still better than a good day at work
