Honestly, if it makes you feel better, you could upgrade, but the club 2000 is fine for your level, you're definitely NOT going to snap the blade (you weigh less than I do, and I wouldn't worry that I could damage any pair of blades), and even if you do move up to Coro Ace's or Pro's in the future you wouldn't have a huge adjustment because the rocker profile is similar. There's always "some" change in moving from old blades to new blades, but it has more to do with the fact that the spin rocker changes as the blades are sharpened and you have to adjust to it all over again with new blades, but that happens even if you stay with the same model.
BTW, my very first pair of "real" skates as a teenager (14ish) was a pair of Risport Super Cristallo's, which is the older version of the RF3.. I had double star blades on those, which are also beginner blades, so it may seem like a weird combo to some, but obviously it is done, even way back then (I'll date myself, that was 1994). I learned all of my single jumps except for axel in those skates. I would have kept the blades for my next pair of skates but they were the wrong size.
