maurice cole metro 3

So i just get myself a 5.10 19 1/4 squad tail maurice cole metro 3 board it has a hardedge rail allover the board.. i get 4 sessions on it and this board flys like nothing else in this world..amazing!! flying to the barrels,cutbacks like i never did theme before.. however my bottom turn i feel like a newbee.. its almost impossible to go more or less vertically to the lip.. it make me think i use to rely to much on my fins and now need to use my rail?!! Is this board really improving my surfing..to learn to use my rail?!
