It's the same old debate whether Hops, Raspberries, Tomatoes, etc.
One side thinks if you trim back the least hardy vines/shoots/suckers and let the 2 or 3 most hardy grow you will increase your yield because the plant will not waste energy on the weeker parts.
The other side believes that if you leave it alone it will yield just fine.
I know with Raspberries, which basically work the same way, you are supposed to cut all but a few shoots.
That said, if you have the space and setup to tie up all of those vines then do it. If you have more tha one plant, why not try both? It will NOT hurt the plant to cut them back or leave them, and then you can judge how you like it.
