If you mean like the Tipplers, I have not seen any raking.
Keep in mind, they are not an endurance flier like the tipplers.
On top of it, there are at least 3 dozen established pigeon breeds used in these squadrons.
They all fly in a very similar way but have some minor differences.
Besides the known breeds being used in these groups I have noticed a lot of mixed birds are also used.
İspir for example thends to be a very common breed (type) and it is a mix of Egyptian Swifts and other breeds, mostly homers and Bağdats.
Keşpir on the other hand is a specific mix of homer and dewlap type birds.
Besides these two mix breeds there can be other mix birds based on the preference of the breeder.
Naturally flight styles vary from loft to loft.
I have however, never seen tipplers in these lofts.
