this being my first post I'd like to say Hi! I'm a 29 year old male from Europe and started surfing about 2 years ago.
Being landlocked and the nearest ocean is 3 hours drive away (Netherlands, not really known for quailty waves

I'm 5'11'' and weight around 170lbs and in decent shape, I try to stay fit for surfing because I can only go for such short periods during the year. (I have a big 6'4'' 40L shortboard to go paddling with on a lake nearby but it's to advanced for me in the ocean).
So far I've been on softboards and a few mini-mals & mals here and there in surf schools and on my own and I'm looking to buy my own board to be more flexible and not having to rent all the time.
Skill-wise I can take off on a 7'6'' minimal fine, can paddle easily to get into most waves I want to catch (lets say 1-4ft european atlantic waves, nothing too steep or big) and can focus on trimming down the line and don't have to think much about the take off.
Frontside I'm trying pumping and small bottom and top turns (nothing major or radical of course) and it's working ok and I'm at a point where I'm at least thinking about a first cutback.
Backside the take off is fine, triming down the line is fine, but the up & down and pumping is still lacking compared to frontside which would be the next step.
I'm thinking of buying my own Torq TET 7'6'' MOD FUN https://www.torq-surfboards.com/fun-76.html (7’6” x 21 1/2” x 2 7/8”; 52.4L) as I know that I can paddle and take off fine with it (and it's comparably cheap and sturdy).
But what about boards like this Modern Love Child? https://shop.surfindustries.com/us/surf/midlength-surfboards/modern-love-child-poly-shortboard/
I am thinking about the 7'0'' (22'', 3 1/8'', 52.6 ltr) cause the volume is similar/equal to what I've ridden before.
The last time I surfed I rented a 7'2'' fish from Torq (which is also around 53L), and that worked good too.
I want to learn properly and improve fast and don't care about not looking cool with the big board on the beach, and I feel that with the funboard I can learn better technique for turning as I can't cheat with my upper body to turn the board around.
Obviously something like to Love Child which is shorter is more easy to move around, but do you guys think it would be wiser to stay on a longer funboard, or is it ok to turn to these shorter/thicker egg designs with similar volume to the mini-mals?
Thanks for your input!
