You are similar to me, the only difference is that I am 5'10. For the size options I say anything between 154 and 158 should be good for you. I personally own a 154 because I tend to like smaller boards, I will write same thing I wrote to love'in life here
A wakeboard for the summer
, thats what I am getting.
Anyway back to the topic Rome Agent all the way, I wanted a board that could handle it all groomers, glades, jumps, rails and off piste. I just got back from testing my board and I love it, the boards handles incredible in every type of terrain you trow at it. It has enough flex and Pop
to handle anything in the park, but it maintains stability at high speeds in groomers. The thing is also a floater by nature in the pow, it's good in ice and corn as well. It's easy to handle in the glades too, I would say that it's the perfect as a allmountain board.
you might want to wait to next season Rome is coming out wish a 154 Slash wich is the sister of the Agent but wider (I believe the board is going to be 257mm wide), so this might help with the overhang of the boots. I personally don't have any problems with it, but some riders might have problems when carving in extreme angles.
Although you might want to consider a larger board maybe a 155 or a 156 will fit your needs better. It really depends on what size you feel it's better for you.
I also wrote this in another post
I love the Agent, I just bought a 154 and tried it at Mt.Hood. My boots are Burton moto size 11, I wight 145lbs and I am 5'9 tall. The setup seems ok to me, I had a little of overhang but nothing to extreme, as long as you center your bindings to the point that the overhang is the same in front and back, you will not feel any problems with drag. Now I am not sure with a size 12 boots how it's going to work. I ride 14/-14, but I next season I am going down to 12/-12, my back knee is going to thank me for that.
The board is insane, it has amazing poop, it has nice flex and it's extremely stable at high speeds. I rode it in all conditions icy, sticky stuff, corn and some sort of untracked snow, not exactly powder but I guess you could call it that. The board floats very good specially if you move your stance a little backward.
I know a 154 is at my lower end of my range, but personally I enjoy shorter boards. Thats why I bought a 154 and not a 156. The boards handles excellent good and it's very forgiving, I only caught one edge in 3 days of riding at Hood and it was kind of a stupid edge.
What size are your boots 11 or 12? if they are 11, I say go for it, you wont regret it. for a 12 size you might wait for more input from other users.
P.S. match that the Agent with a pair of 390's and you have a dream set. That setup is so responsive and stable, I never rode anything like that before.
