Well the only real reason I don't wish I had a displacement hull is the fact I learned on Planning hulls...I'm sure if I learned on DHs I would prefer those.
I did like the Jefe...not paddled the Grande but I'm sure it handles the same. It punched hole fine, boofed, rolled etc fine. I just feel and its been said that once you get started in the direction you want to go, the burn will get you there. I feel like I had to work a bit more on ferrying etc in the Jefe.
I've never had an issue with the "vertical" side which isn't vertical...However, I've never really "T-pinned" on a rock yet
