We played with the rules this weekend and really enjoyed the initiative rules. Ships on each side were as follows, with me as the Brit player:
Brits - Leviathan, Medusa, Charger, New Zealand, Beagle, Anfield, Trafford
French - Jean Bart, Pontbriand, Ardent, Lave, Dupuy de Lome, Grenedier, La Gloire, Montcalm
My concern was that the initiative balance between classes might be really disrupted, giving BBs a disproportionate advantage but actually we found the rules didn't disrupt gameplay too much. For myself, I usually moved my DDs first and alternated the CLs and BBs depending on the turn. Charger was running down the back of the French line and NZ was running escort on the BBs, while being able to shift location and bring a new target into range. The fact that we were also using the elevation rules made the BBs more mobile and much more terrifying.
