Spec TC: The lightest one but the more fragile one. Seen by many as a race day only tire because of being prone to punctures. 24mm is 24mm and 26mm is 26mm
Veloflex: 25mm is a true 25mm. Some people say they are smoother than the Corsas or the tire the Corsas aim to be. Not enough info on puncture resistance or any other difference. Apparently more affordable than the Corsas but I have yet to confirm this.
I rode a set of Turbo Cottons until the rear was square and didn't have a single puncture. They are quite tough actually. They are heavier than the Veloflexes. G+ are even heavier though.
All 3 are excellent tires. Veloflex are a bargain. They do run narrower than the others, which is a plus in my book.
