Tall guy, improver board advice!

Hi all,
I first posted back in 2018 for advice on my first longboard and have been riding 9ft 3’s ever since thanks to the advice here.
I definitely feel I’m at the stage where I’d like to try progressing to something more manoeuvrable - I don’t get out loads but recently went up to Thurso here in Scotland and when on waves thought I’d like to be able to turn more easily etc.
I’m 6ft 5, fit, and around 94kg. So looking for advice on what would be a wise next step to start getting out and practising turns more easily (and hopefully getting out a bit more easily too….!)
Won’t be surfing any huge waves. I saw another thread with a guy, better than me, and a few inches taller and heavier who went with a Channel Islands OG New Flyer, 6’4” and 40L. Wondering if that should be my sort of ballpark too?
Any advice appreciated and thanks again everyone!
