Replying to Dalbello IL Moros or K2 B and E

Ok so I’ve been really trying to decide between the B and Es and the dalbello IL moros, I’ve already been to a boot fitter and I need a 25.5 and have already tried the B and Es on and they felt great. I also had the dalbellos earlier this season and loved the performance and snappiness of them but had to sell because they were too big. I am 15 and only weight about 125 pounds, are the dalbellos going to be too stiff at 120 flex? Would they still work with FT tounge with a softer flex? Or should I just go with the B and Es that I tried on?
