It would seem I am now forced to eat some of my words regarding warlord, found out the support boxes are fixed head, went and asked mail order if I ordered a 'normal' (ie separate head) hq, would they switch it out for me and to my great surprise the lovely Robin at warlord was happy to help even though it meant extra work.
Also I ordered on Tuesday night, dispatched yesterday and arrived today...pretty good service and a big thank you to Robin Scott-Blore!
