I rough-cut the middle top skin today and located the first two holes. What yo see in the picture below is actually clecoed in place. If you're reading this and on the fence about whether to build the old or new style canopy, from a building perspective I'd say go with the 650. I had expected things to be a little more difficult, but this tube frame mess is hard to get right. I can tell immediately that I'm going to have to trim the outboard edges of my tubes down. This is fine per the photo guide. I'm now seeing the dreaded "compound curve" I've been reading about too. No worries. I'll get through it, but it's going to be very time consuming. I'm really picky and I didn't come this far to have things start looking like crap now. It's a big day though and I'm excited!
