I love my Summit Titan aswell. Being smaller, only 5'11'' 180# [all muscle lol j/k.]
it has plenty of room. All I've ever had were bare bone climbers and loc-ons, no padding nothing. Then I got a 120 dollar climber from Wal-mart with the web seat and padding and thought it was the greatest thing on earth. Then I got the summit and WOW!
So my expierence is limited..... but love the Titan.
