Good to read that you liked the board Kisutch and that it's not tiring on the body. You could have gone lower in volume but maybe you didn't have than a 3h session. It's difficult to compare a shape like that to your Blurr 8"x28" because of the wide tail and outline it will be more stable as you described.
I'm curious if you have to push the tail more than the Blurr because of the tail and how it turns with the quad set-up. Curious how fast it is down the line compared to your Blurr, and if you have used it again in the conditions you got it for.
My experience is that the Gong Mob 7'6 (105 liters) with a wider tail than the JL Destroyer 7'7 (100 liters), you have to have your back foot on the kickpad, and if you too the board will turn how I want to. It takes a bit quicker the waves and it has also a bit more glide. For me, both boards feels stable and I can just say there is the 5-liter difference so the Mob is slightly stabler but I can go out in the same conditions. So in the end I think both are suitable for small waves. I haven't really formed an opinion which one is quicker, I can throw around the destroyer a bit quicker because of the thruster setup and the pintail because it's a bit more forgiving with the placement of the back foot.

So I can't say I found the Small wave machine board just yet because I have the same fun on both boards, it's not that the Mob stands out over the JL Destroyer. It is however a good addition to the quiver. As I said the Mob takes a bit quicker the waves and with the added glide it's better to grab that one than the Destroyer but when there are really nice waves with some push in it, I will take the Destroyer 10 out of 10 times.
