Question / Problem with Routing

Hello,

i have a question about a little routing problem

my network-schema looks:
routing.JPG
i have set a default route for the internet-connection and a backuproute:

 # DST-ADDRESS	PREF-SRC	GATEWAY		DISTANCE
 0 0.0.0.0/0			172.16.9.5		1
 1 0.0.0.0/0			172.16.9.9 		2

and now i want to route the eoiptunnel 01 over the gateway172.16.9.5 and the eoiptunnel 02 over the gateway172.16.9.9.
to set a routing mark works, but the mikrotik is not powerfull for this action. with the routing mark, the load will be 100%.

have anyone an idea to solve my problem?

thx for helping
