I have never seen/used a Bowfin2 but I do have some experience with the company--I have a Tarptent Moment (single wall) that I have put at least 2000 miles on. I am 6'2" and often used the tent with company (2 people in a 1 man tent-company was always romantic ) .
The floor on my tent is 84" long. Yours is 102". Interior height is within 4" of each other. Here's my experience. The tent will get the job done, but you are not going to have enough room to sit up and play solitaire. Though in your tent, you might be able to prop yourself up a bit more than in mine. The one thing you may have to get used to is how close to your face the roof of the tent will be when you are laying down, though I think yours will be more spacious than mine due to the longer floor length.
Tarptent makes a fantastic tent. I've had mine for 5 years, used it more than most will use a tent, and it has almost zero noticeable wear. When I camp with others, I am always the first to be set up--these tents pitch super quick.
I have used it in horrific rain storms, snow storms where I got 8" overnight etc. I would recommend the Tarptent Brand without reservation.
Here's a video of me setting up the Moment and laying down inside. You can get a feel for how tight it is. Keep in mind I lived in this tent for two 3 month long backpacking trips in addition to weekend trips/hunting trips. Your tent will be a little heavier, but much more spacious due to the increased footprint.
