i have been thinking about a property about senju and uzumaki ,
i think they are better compatible with foreign chakra .
1 . NARUTO UZUMAKI - definitely mixes his and kurama chakra all the time, and not only this he had masterd the sagemode which is another example of foreign chakra in your body plus has now shown he can change chakra type while giving it to different people ,(an uzumaki)
2 . kinakaku and ginkaku (uzumaki) = showed abilty to control kyubi's chakra .
3 . Hashirama = mastered sage mdoe
uzumaki as we know they are distant relative to senju and senju's are more compatible with sage mode as they have so6p body feature, it will be pretty obvious to say that uzumaki are also better compatible with sage mode .
