Thanks much for the suggestions, I'll be giving them a try right away.
As far as number of mechs, yes it is fairly large, but part of what we were looking at was having many of the mechs unique to only one or 2 civs, several that would be common for IS/Clan, and a few that would be common to all. Without taking the weapons systems into account (at least in as complicated a way as you would have to in BTech/MW), that concept meant that each civ would need several of each class (light, med, heavy, assault). And I was also hoping that they would be dependant on the tech tree, but thats a part of the mod I havn't developed much yet. But your point is noted and taken, if it will slow down the game then by all means just use that list as a starting point and help me whittle it down.) I can start with those models, get some help converting them to Civ units (nudge, nudge, wink, wink), then we can add em till we're happy. Or just keep em for others to add or delete as they like
