Vine trellis idea - criticism welcome

Hello all,

I'm looking at making a trellis system for some vines at my home. The typical trellis you see has a center post, a perpendicular beam, then 2-3 wires on each side going to the next trellis post.

For my idea, I'd like to offset my beam by making it 2/3 on the right side, then slanting this 2/3s up 15 degrees. To offset the off balance, I'm thinking of running a 2x4 from the center of the post to the left end of the beam. I will only place the wires on the right side, the 2/3s. This would be built out of treated 4x4 post, and 2x4 beams/supports. i could upgrade to 2x6 supports if needed. I couldn't post pics, so I attached links. Sorry for the inconvenience.

Thoughts or concerns?
Think this trellis idea will be strong enough to support heavy vines? Better question... how much integrity am i losing by going this route?

Thanks for your help!

 

What vines are you using......are you going to use coated wire.....is that a concrete base....?

 

A couple Hardy kiwi varieties (ana, oaks and issai). In about 4 years, there could be some serious weight (100lbs ish).

Cement will be used, and we're in hard clay. Coated wires, just like I use for my micro vineyard.

This project won't be my first trellis, as I've built them for grapes and have also built fences, arbors, sheds, etc. However, the truth is I've always piggybacked off other ideas or at least a combination of. Since I'm going with an idea I've never seen used for a trellis system, I'm a little leary.

By the way, I got this idea from some crane structures. Figured if they could not only hold, but lift heavy stuff.... my semi stationary weight should be okay

 

I had a neighbor in CA who had 20 y/o kiwis. No trellis, they rested on the ground. A hassle to pick and prune.....
