i mean it really depends on what you want. if you just want like an in between freestyle board then it just look into some of your options and go for something that is somewhat flexible but not a super noodle.
honestly, a softer board might be decent for you because it will be more forgiving.
best bet is to figure out the size that you need first. then go from there.
if you think that you might progress quickly then maybe Wrath's idea of doing a seasonal rent would be a good call... again it's up to you.
