(Yesterday, 7:22 pm)Michael wrote 421 seems to be getting used on the 599 quite a lot, has NEXUS asked for a decker to be used?
Purely down to E200 availability I would assume. The 79 has to be one so if you only have two available then the other 599 has to be something bigger. The E300 has been off for a while (due back shortly I gather) so therefore have to throw a decker out.
