My preference would be a route number per service, even if it is only slightly different.
I think letters only work on certain services.. 2/2A example, routes which have loads, such as the current TEN brand can be confusing.
Like before the old Laser brand is the biggest example for to many letters.
I think its reading where they use decimals for services like 7.1,7.2,7.3 not sure thats the routes but its an example... to me that's more confusing than to many letters haha.
