Hmmm. I am going to decide in the New Year, as my plans for 2016 aren't anywhere near being settled yet.
There will be drop outs so there being 100 filled places (as looks certain) at this early stage is mostly irrelevant.
And if the waiting list turns out to be oversubscribed by the time I decide, then I'll just tackle another hilly 1000 as a perm, probably a group perm. (My plans are at least certain enough for me to say I am going to do a 1000km ride, as I want to achieve an R2500, which I view as the purer test of my Randonneur ambitions than an SR.)
