More inches make a difference

Confirmation that the Brompton S2L was a handicap at the BWC. I was lent a P6R by my local Brompton dealership and the longer gear inches offered by the Sturmey Archer hub helped me achieve a new personal best time in the silly commute race today.

I'm in a dilema now. Aiming for a top 50 placing this August, should I modify my S2L or sell it to buy a new version?

I think I'm going to embark on a journey of modifying it.
