best bet is to post in the newbie questions area
Cant really be much more help than that though as you're probably on a similar level of game to me to be honest, although i always feel one long opinion opener or two short ones is about right and after that its kind of dragging itself out so making it into a situation you have to recover rather than progress from if that makes sense?
I couldnt help but feel from your example the second opinion lengthens it to the possible extent of being on the back foot to progress the conversation.
