Hanelei fins offers the option of shallow or deep futures boxes when you order! Placed an order with Robin and he emailed me directly about them.I don’t know twinzers but if he messed up the boxes, I’d be surprised if they were placed correctly to use the futures canards. Seems like Twinzer bros are pretty specific about “Jobson” placement. If not, I would have him remake it to what you ordered. If they are, I would have him replace the rear boxes. If not him, your best ding repair guy could probably do it.
just my 2 cents.
Hanalei stuff looks weird but they work and Robin has excellent customer service
Only shallow futures box twins I could find online
