Heyneke Meyer believes the nation that is crowned World Cup winners next year will need to have a mix of experience and youth.
The coach of South Africa has recalled a number of thirty-plus players for the forthcoming internationals against Wales and Scotland later this month.
Among those in his squad are locks Victor Matfield (37) and Bakkies Botha (34); hooker Schalk Brits (33), scrum-half Fourie du Preez (32) and loose-forward Schalk Burger (31).
Meyer also called-up seven uncapped players in a 36-man squad for Tests against the Welsh on June 14 and June 21, as well as Scotland on June 28.
With the 2015 World Cup in England, in mind, Meyer said: "I watched Toulon win the French Top 14 final last night and saw the role experience played in their win.
"Most of the successful teams around the world have many experienced players. Some of them have been written off but some of them move on and become superstars.
"The youth brings enthusiasm to the squad but we need a balance. Some of the players who have moved on have become superstars in another country after they were written off in South Africa."
Burger and Matfield have not played for the Springboks since 2011, Brits since 2012, while Du Preez and Botha returned to the fold last season, along with centre Jaque Fourie.
Fourie was not considered for this squad due to injury and neither was Jean de Villiers who is absent with a knee problem.
The uncapped players are centre Damian de Allende, lock Lood de Jager, wingers Cornal Hendricks and S'bura Sithole, loose-forward Teboho Mohoje, prop Marcel van der Merwe and hooker Callie Visagie.
