Hi there. This is my first post. I just got a Biria Easy Boarding 7 and I already custom ordered a laid back seatpost from Slowriderz. I want a super comfy saddle. It will be an upright ride. I wanted to get the b190 as it looks the widest and most comfortable. However, I am 5'5" and about 120lbs, so not a huge person. It says this is for heavy riders...will this work for me, or am I better off with a b135, b33, or b67? Also, is the aged leather much more comfortable then the regular leather? Thanks in advance. P.S. I am very new to bikes, so I just want something comfy for casual rides (I don't mind breaking it in though). Just got a Giant Wald 157 for the front to put my little dogs in.
