Can I be cynical and suggest LiPo are only being allowed this year because Schumacher have one to flog now?
After all, they aren't any 'safer' than before, and still don't fit in alot of chassis, both of those reasons were given about why they weren't allowed last winter.
I only run LiPo at the moment, and I managed to borrow some stone age technology (IB4200's

) for the first round last winter, but I'm tempted to find a B4 for this.
