Exactly the same with me Souwester.

I started to SUP from a shortboard. Well it was a 7ft board & I just couldn't get my paddle speed & courage to drop down that steep wave face. And when I did, I got smashed! But did at times get a few good rides. But hard work since my young fearless glory days.
Then along came my older work mate who heckled me to get a SUP. I just blew out watching him get onto those big freaky waves on something that resembled a boat! A 10 or 101/2 foot Coreban. Then a shorter SUP.
So finally gave it a go on a 9ft 6" Vex Profusion. Sooo frustrating! But after 20 sessions it came more natural. Um well, twisted knee, sprained ankle from jumping off the board into shallow water, broken rib, deep cut behind the ear from board spring back & deep cut to chin from being dumped! Lol! Oh, and banged on the head that broke both my skin & the board's skin. Lol!
Then one day my paddle broke. So decided to prone surf it & loved it. So got my old 8ft mal out. Loved it. So bought a 6ft4" Surfboard Warehouse Zephr shortboard & got the hang of that. And since then a square nosed 6ft 4" Sunova Darth copy of a Firewire Vader & a 6ft 6" Soul that I use as a single fin. Love them all.
And since then about 6years ago. Less injuries & met up with some great surf mates.
And now getting into foiling. Love it. But will never let go of of short boards & mals.
But what I must say. Getting into SUPs got rid of being intimidated by big waves. So at 58 years of age I am slowly getting back to my younger days of late 70s to 80s thanks to being introduced to SUP surfing by my mate who is sadly having serious back issues at age 68 years. He was one of the first on a SUP at my home breaks of Windang & Warilla. His name is Butch, Geoff Young. I owe it to him for re-opening my surfing world. Sorry for the ramble on.
My SUP quiver at about 80 kg weight more or less.
Sunova Soul 8ft 3", JP Widebody 8ft 2", Jimmy Lewis Super Tech 7ft 10", Coreban Wahine/ Hyper 7ft. Using this as a foil board as well.

And shortboards mentioned earlier.
Love them all! And keepers.
