Hi Jason,
Sizing sounds ok - although if you use Warps, I would really say long term you should think about moving to Jag or Falcons, to get the most out of the sails. Board width sizes:
115 OFO 45 and 10cm from tail.6
100 OFO 42.5 and 10cm from tail.9
Re Fins I canĀ“t comment too much on Gasoil to be honest, I think 115 best sizes probably 36-39cm, for the 100, try 30-34cm...
