Not a Vader but i have started surfing a Thomo Vanguard. Also a 5'10" whilst my normal board is 6'2" and I'm 95 kilos. I also agree the vanguard paddles and seems to catch waves much easier than my Dominator. It has sadly been mostly only small stuff since I've had it but it really feels like a go to ATM for me. I've got no idea about the technical stuff but it feels great, i like short boards as they can stay in the car and its light when having to lug other boards (kids) down to the beach.
Get used to all the questions about "did you snap the nose off" and "What the hell is that thing?"
I wanted to buy one last year and everyone talked me out of it, i then bought my dominator and travelled with that OS. But TBH i regret that big time. I think the Vanguard would have been so much fun in the bigger stuff
