Cylinder Size Question

I just received a 1.75” cylinder last week and am wondering if it’s too big. My older 1.5” cylinder which is 4.5” inner diameter is completely packed. My base girth is about 4.75”, mid shaft 4.5”. I seem to be swimming in the larger tube (4.25” i/d), however, I do get more pumped length in it using less pressure vs. the 1.5” tube. The larger tube is packed for only the first inch or so. Will I grow evenly into this tube, or should I break down and get a 1 5/8” cylinder?
