I have both the Innova and the Titan in play at The Goat Path near Mammoth Cave, Ky. Titan stands about an inch taller and has a slightly deeper trap with heavier chains more like a Lightning DB5. Both types will rust. I have added 6 inner chains to some of both and they work well. Titans are better at holding aces than Innova if you don't add chains and make a very satisfying ching. I asked Mando about his experience with both Titan and MVP Pro after he bought both. He recommended MVP but I ended up going with Titans for cost and the depth of the trap. I already had extra chain from my home made baskets so single vs double wasn't an issue for me.
