I concur with TubeDude on the mountings.
Since the Emotion Spitfires are hard plastic, there is no harm in drilling a few small holes and sealing them with silicone. It will not affect the integrity of the floatation of the Kayak.
I had a 2 man Malibu tandem kayak for a few years. I actually mounted the Scotty deck mount rod bases. I had 4 of them mounted so that I could troll a line will rowing and have the other rods on stand by when the bite was hot in the ocean.
Silicon was enough to keep any water seepage. You can always supplement your rod holder abillies with the Pvc tubing in the milk crate technique too. You will only limit your casting depending on your type of fishing.
When I am flyswatting from the Yak or tube, I prefer to keep the other rods on a low profile or even on a horizontal rack. I go the horizontal idea from TubeDude. He is a genius when it comes to crafting ideas for any type of floatation device.
He also make a good TubeDad. Bass are toys. Gills and Trout are food. There is a fine line between fishing and standing on the shore looking like an Idiot Fast, Free Registration Tell them TubeN2 sent ya
