Merry Xmas all

So I've been paddling flatwater, surf and also downwinding for the past year, so fairly new to the sport. Weigh 75kg. Current and only boards i've owned and used are

2014 Fanatic Falcon 14 x 27"
2017 Fanatic Strike 14 x 24"

The Falcon is extremely stable in all conditions and downwinds and surfs nicely, but feels like a truck on flatwater and buoy turns. So if having a workout on the bay it's not as fun with the little glide per stroke. The Strike is fast and light, great glide, and cuts through bumps beautifully, but I find it very unstable, although I'm sure this is also due to my limited experience/skill. Even in small chop I'm only fine so long as I'm with or against the swell, but as soon as there is a side swell I'm shaky. Also find when sprinting I am able to hit only perhaps 90% as some effort goes into stabilising.

I was thinking of selling both boards and getting something of an all-rounder that is still quite stable but also sharper at the nose than the Falcon. Briskites have a very nice Infinity Whiplash that looks fast, but I wonder how it would go downwinding/technical/surfing.

Was hoping a few people might share their experiences.

Thanks again and hope everyone is having a lovely Chrimbo.
