Just use your spod rod bud...…. A decent marker float and lead is quite a payload...….. Marker rod is generally too soft for spod work at any real distance but a spod rod will be ok for markering……… I'm looking to buy one myself after giving my 3.75 marker rod away, it was a bit soft for getting a spomb out too far. OK with mini spomb, but that means more casts...……….. Your spod rod will be ok for markering, less kit to lug about, too ,with just the one set up...…. Just tie a big loop in the end of the braid and you can quickly interchange marker set up to spod and vice versa...…….. Find a spot with marker set up, clip up on reel, quick change to spod set up on same rod, and you will hit the spot bang on when baiting...…...Allow for water depth if it's a tight spot..
Depends really on how much you need to fine tune your markering, or whether you are just looking for a clear spot...….
