Answer provided by the Sunova mascot:
Yes.
If you can handle the 9'2 Stun Gun, you can handle the 8'10 Speeed.
While the width will challenge you, the wider nose gives a ton of paddling stability and the nose kick make it very forgiving on the drop.
I ams 104 kg and the smallest Stun Gun I would be ok on is the 9'7.... but the 8'10 Speeed was my goto board for over a year.
It sounds like you adapted to SUP very easily, so although the 8'10 Speeed will suit you at the moment, you will soon be ready to downsize to the 8'8.
The 8'8 would be a challenge to learn on for sure, but if you are willing to do the work and suffer a bit.... the numbers work for you.
