Second board advice

Hello. I've been surfing in Japan for about a year. Bought a 7'6" last year and kept it at the shop, but I've been making more friends with cars and heading out to some other breaks. Unfortunately my 7'6" is really just too big to get on the train, even to head to where everyone is loading up the cars. It's too big for some of the cars. I'm looking at getting a second board, a little shorter, but still something fairly easy. I'm 66kg, 39 yrs and in average shape. I get out once or twice a week to surf, on weekends, so I have to take whatever the conditions are. I currently have a Santa Cruz Solid, probably low 50s in volume. I'd like to get something around 6'6". I can stand up fine and catch unbroken waves. I'm working on turning and going down the line. I know it would be ideal to wait a little longer to get a board, but I really need something I can travel with now. I've tried some 6'8"ish boards probably in the low 40s in volume and I have been able to catch waves and stand, but definitely more difficult than a larger board.
I'm looking at this board now. 6'6" Three Weather Happy Turn. (Yeah, I know the name is a bit silly. It's a Japanese brand) The price is ok. The volume is a little higher which should help with mushy days. Has some nice flexibility in fins. Concave in the nose. It seems like a better choice than a groveler/small wave board.

I've also looked at the 6'8" torq fun board. The 6'10" torq big boy 23 (probably a little larger and more volume that I might want). I'm curious about the McCoy nugget, but it's twice the price of this board. I'm not sure if it would be worth it at my current level. Probably worth waiting until I improve more. Firewire is too expensive for me in Japan right now. Lost is up there with McCoy, but not off the table. I've kind of been warned away of going shorter than 6'6" until I'm able to go down the line and stay in the wave.
How does the above board look? Any suggestions on other boards I should maybe look at? I'm restricted to Japan at the moment, but I can consider getting something next time I travel back to the US. A lot of brands are considerably cheaper there. I've been watching the used boards, but haven't seen anything pop up in my size/volume range for a decent price.
