Ok so, the 5-string will have to wait. I have decided to purchase the 4-string bass in the same series in the last moment, mostly because someone said something that made me change my mind.
I have 0 technique. According to him, starting on a 5er breeds lazy habbits since you have to move your hand less. As such, i got the SR300 to work my hand on that fretboard haha. The 5 string will have to wait for now
but thanks everyone who participated in this thread, i now know what to look for in a 5str'
