Check PBs to see what strats are used for the routes. Some levels are worth switching for a different one, if you can't do the corresponding strat. For example 3-12 with Josef only saves time if you do it first try, so you can switch it for another level, etc. Other kinda worth it bandages not included in these routes are 2-5x WZ, 2-12x and 4-16.
