Old Style Javs

[Gamey]

We have several of the old style javs which we sometimes resort to using due to numbers wanting to throw (in training).

My question is can these be re-gripped to make them legal or were the changes made too much to be able to make them comply with the new rules??

i estimate that we have 3 X 400g, 3 x 600g, 2x 700g & 1 x 800g - so a fair bit of kit sitting doing nothing most of the time.

the only ones that would need to be changed if it is possible are the 600g javelins and the 800g javelins. the others have not had their specifications changed
