OK. Getting close here. Helix is the choice. For what I do, the LT looks like it would do everything I need. I've got one "pro" saying "if you don't need the added I/Os, definitely go LT". I've got one "pro" saying "get big brother, you'll be glad you did". What say the modeling forum? LT is all I'll ever need Just shut up and do it. Get big brother.
