I (54yo, 6ft, 165lbs) have the 6'6" 48L Addvance, it's great! It paddles really well and it catches waves easy because it holds a lot of the volume in the front so u can put ur weight forward to make the drop while the shortness and strong nose flip prevents pearling.
I also have a 8'2 Submoon I like a lot and a 6'2 Hashtag for steeper waves. After surfing the SM for some time it's hard to go down to the 6'2 # because the takeoff can feel very wobbly, but stepping down to the 6'6 Add is no problem because it's almost as stable as the SM in takeoff because of the width in the forward area.
With small thruster fins the Add offers a surprising lot of performance in oh+ and I can connect to inside sections by stepping on the nose to trim tru the weak stuff. I can even duckdive it in medium (Head high Bali mind you..) whitewater walls, it's a matter of timing the 48L goes under in slowmotion..
Now you could go for an 6'8 or 6'10, but I think the 6'6 is the one. It's already huge and thick for a shorter board.
I had a Dominator 6'6, that's the exact same shape as the Spitfire apart for the step down tail. (at the time I went from a 7'9 malibu to the 6'6 Dom without any problem. Was up and surfing the walls first time out) But the wide tail of the BIG Dom was too much for the Baliwaves so I sold it.
For your weight surfing 2-3' mushy waves (I assume you mean 2-3' from the back of the wave right?) the Spitfire 6'4 is perfect.
I cannot speak from experience surfing the Greedy Beaver but as it happens I was feeling up a 6'0 (37L?) the other day in the shop, I liked what I saw a lot, I would love to try one some day.
If ur interested in a GB the go to Boardformula.com and compare it to ur Spit. Look at the tail width especially, the narrow tail of the GB needs a wave with some push. The wide tail of the Spit is perfect for those 2-3' mushies, just put in the effort and the board will come alive

But like I said earlier if u want to make it easier on urself get something in between like the Add or something longer and less bulky.
