Hi Alex, thanks for the trust and investment in our brand, we appreciate it! I would go for a Mamba or FreeWave, in approx 85L as a start since you have little wave experience/also want to use it for bump and jump. The FreeWave 85 would be the first choice and will work best for both. The Mamba 84 better for wavesailing, not as good as the FW for flat water? You could go smaller but not sure if you have ever ridden smaller boards before, as you are fairly light, your ideal "wakeboard" would be a 75L size - but then you need some experience first- then I would choose a Mamba 78 or FW75, with same characteristics as the 85L models.
