Blootac, I know I have to be extra careful with lifting, that's why I do lots of exercise and workout to keep my back in check and prevent that kind of injuries.
Gurnard, you're right. It's just a plan and things have to work out for me so I can put it to action. Future will tell.
Max, my 320 Suzumar is too big to be inflated in my roof top so the 380 is out of question. I will carry it on the roof top when I'm with 1 or 2 mates and inside the car when aloen or with my gf.
