i didnt know how long you had been playing, i just knew you were a beginner, but i guess you are more experienced than i thought.
i would actually advise you to learn both ways, and then play with which ever one you like better. learning both will teach you more limb separation and you will be able to control your movements better. i have been too lazy to do this, but i will eventually
when it comes to music, learn everything you can, even if you can do without it.
it will be harder to learn open-handed since you have already learn crossed, but like i said, knowing both will benefit you alot.
