The original Microlite, Titan, Avenger series and the subsequent Microlite, Titan, Avenger 2000 series (probably the 3000s as well) were all designed by or had input from Geoff Salisbury before he went on to design the Carbotec range, the later Mk II 13-14s were made in China not Japan and are very different rods. I like the Mk II Microlite 13-14 that I have as it's a versatile very light actioned rod. Whether the Titan Mk II 13-14 you have is any good I can't say; I've seen them but not fished with one but if it's a light, forgiving rod that you enjoy using then do just that. I have had my Titan 2000 for over 30 years and it's still a rod I use a lot together with an Avenger 2000 that now looks battered.
One Normark rod to avoid, in my opinion, is the Crusader series.
An under-rated but cheap (the blank is much cheaper than other Normarks) is the Vantage Super Match which is a very nice general float rod with a lovely action. I sold mine on for what I paid for it as I have enough rods!
