Hi - I have both the Guru and the Milo Pole Case. The guru would be tight with all that - use mine for spare 4/5s for the river. With the Milo i have a 13m pole, 16m pole, spare4/5 and 10 kits. They are great. The Cresta is pretty much identical.
Try North Notts Angling for a Cresta or Bordon for the Milo.
