No, I will probably get on the list for a mantis and look for an interim solution.
I'm frustrated as well; but I can't complain, I can just try and find solutions. I was one of the first to order a platform, but because I live in Canada, I still haven't received it. No big deal, I found a solution to get it in my hands. Couldn't be happier, or prouder of the guys that put it together. Really cool stuff man.
I've got the interim solution for you buddy. I've got a rock climbing harness and a sitdrag I'll ship to you. I put it together mid season for me last year and hunted out of it after an hour of shooting practice. There's really no learning curve in saddle hunting unless you're really afraid of heights. Use your stepps to climb and as a platform - you're laughing bro! This year I'm doing the fleece saddle because I find it more comfortable. PM me your shipping info and I'll get it out to you. My only request is that you ship it back to me when the season is done.
Welcome to Saddlehunter. If you take care of the guys here, they'll take care of you.
