I have the Unrigged Explorer and find it heaps big enough with all the gear loaded on (I am 5’11). At 6’2 you would fit just fine as I have leg room to spare in mine. The other raft in the pics is a Denali Lama, a bit smaller but Gus loads it up and still fishes easily. They are designed to have packs strapped onto the front (as you see in the images) they actually paddle better with all the weight up there, they balance really well (they are called ‘packrafts’ after all). If you order one get the Backpack Attachment System at the same time, they are the business for putting the pack on the bow, a very simple and sexy system.
Comparing the Lama and Explorer, I would get the Unrigged Explorer again for fishing, they only cost a fraction more in the big sheme of things but the extra internal space is a good thing.
Where are you based? you are welcome to have a go in mine if you’d like. I am based on the far south coast (Bega). There are a few others in Sydney too that you may be able to get a paddle in
