If you're using LFC Marshall's update, then I'd suggest Swindon in League 2. Easy chance of promotion, good squad (possibly a bit too large!), but with some debts that will need to be well managed long term. Otherwise, if you prefer to play with financial constrainsts, I'd suggest Crawley (League 2 with the update, BSP with the standard database). Luton in the BSP would be another good team, as they are one of the better teams in the BSP.
